Agilent 8753B Network Analyzer Firmware History

Revision 4.00 was the original release.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  1. In the CITI file (ASCII data file storage) application:
    • data is incorrect when more than 401 points are used
    • response and isolation calibration arrays are reversed
    • one-path two-port calibrations could not be saved
    • choice of binary or ASCII file storage is uncoupled between channels
    • only one formatted array is saved if a full two-port calibration is on
    • in log mag, the formatted data says it is linear even though it's log mag
  2. When using the maximum number of list mode points:
    • full two-port calibration cannot be performed
    • data into memory does not work correctly
  3. Reading an Agilent 8753B instrument state from disk leaves the default printer type as COLOR, which will print incorrectly to a standard monochrome printer. One place where this causes a problem is in SYSTEM VERIFICATION.
  4. If frequencies are changed with limit lines on, the limit lines do not move to their new places on the display, although the limit test still works correctly.
  5. Occasionally, display characters are blanked at preset.
  6. If a full two-port calibration is performed and then CW time mode is selected, bad data results.
  7. Waveguide calibration kits do not work correctly.
  8. In a one-path two-port calibration, the instrument prompts the user continuously to turn the device around.
  9. No installed options appear in the firmware revision information when an instrument has option 002 but not option 006 or 010.

The 08753-60207 phase lock board was introduced to allow RF less than LO mixer measurements. This board must be used with Agilent 8753C firmware rev. 4.02 or higher, or Agilent 8753B rev. 3.00. It is NOT compatible with older firmware revisions (Units will phase lock with A9 CC jumper in ALTER position, but not in NORMAL).

Firmware Enhancements

  1. A new softkey menu has been added for frequency offset mode. The improved user interface includes a diagram which makes it easier to set up the network analyzer for mixer measurements. A new capability for making measurements where the RF<LO frequency is automatically enabled if the appropriate A11 phase lock assembly (HP part number 08753-60207) is installed in the Agilent 8753C.
  2. Faster data array transfer to an external controller is now possible when using FORM1, FORM2, FORM3, or FORM5 (not FORM4). The new HP-IB mnemonics and their normal-speed equivalents are shown below.
        OUTPRAF(1-4)  OUTPRAW(1-4)   Output current raw data
        OUTPDATF      OUTPDATA       Output active channel corrected data
        OUTPMEMF      OUTPMEMO       Output current memory data
        OUTPFORF      OUTPFORM       Output active channel formatted data
  3. The Agilent 8753C automatically switches to system controller mode when necessary if no other controller is on the bus.
Firmware Problems Fixed
  1. Controller-based plotting using the OUTPPLOT command did not work properly.
  2. Interpolation was done on 2-port calibrations whenever the user switched from measuring one s-parameter to another.
  3. When "INPUDATA" was used to input FORM4 data arrays to the instrument, an extra 0 was added at the first point. This offset all the following values, causing real data to appear as imaginary values and vice versa.
  4. Sending titles over HP-IB into a sequence occasionally appended the title instead of replacing the current title.
  5. Recalling an instrument state from disk which had formatted data and user graphics did not update the trace.
  6. Data and instrument disk files which are created by an Agilent 8753C with revision 4.02 firmware are compatible with other Agilent 8753B or Agilent 8753C network analyzers.

Note: See the 08753-60207 phase lock board warning in version 4.02 above.

Firmware Enhancements

  1. New softkey menus have been added for fixed and swept IF frequency converter measurement configurations. The menus also allow control of the Agilent 8625A external LO over the new LO control interface (contained on the A16 rear panel assembly HP part number 08752-60013).
  2. New HP-IB mnemonics have been added for programming fixed and swept IF frequency converter measurements from an external controller. The new HP-IB mnemonics are listed below.
        ADDRLSRC          external source address
        DCONV             selects downconverter
        EXTTHIGH          low to high external trigger ON 
        EXTTLOW           high to low external trigger ON
        LOCONT            external LO control
        LOFREQ            frequency offset CW (was VOFF)
        LOFSTAR           frequency offset start frequency
        LOFSTOP           frequency offset stop frequency
        LOFSWE            frequency offset sweep frequency mode
        LOPOWER           frequency offset power level
        LOPSTAR           frequency offset start power level
        LOPSTOP           frequency offset stop power level
        LOPSWE            frequency offset sweep power mode
        OUTPICAL(01-12)   output interpolated cal array
        OUTPIPMCL(1,2)    output interpolated power meter cal array
        UPCONV            select upconverter
        VIEM              view measurement
        FREQCONV          frequency conversion measurement parameter
        LOIFISOL          LO to IF isolation measurement parameter
        LORFISOL          LO to RF isolation measurement parameter
        RFIFISOL          RF to IF isolation measurement parameter
        RFPRTSWR          RF port match measurement parameter
        IFPRTSWR          IF port match measurement parameter
  3. A new softkey menu now appears under the MEAS key if one of the frequency converter tests sets is being used. These test sets are the Agilent 85046A options H20, H21, H40, and H41.
  4. In frequency offset mode, power meter calibrations are performed at the source frequency. In earlier firmware revisions, they were done at the receiver frequency.
  5. Bit 7 of the status byte is now defined as the PRESET bit. This allows an external controller to detect when the preset key has been pressed.
  6. The maximum number of calibration data sets which can be stored in memory has been increased from 12 to 24. This limited by the amount of memory space available.
Firmware Problems Fixed
  1. The power loss table used some of the same memory space as internal register 5. Both the power loss table and the cal factor sensor B data have been moved from CMOS to RAM. Therefore, this data is now erased if the power is turned off.
  2. In test sequencing, if a user changed the number of points and then immediately performed a calibration, the previous number of points was used for the cal array memory allocation.

Note: See the 08753-60207 phase lock board warning in version 4.02 above.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  • The HP-IB command "INPULEAS" for inputting a learnstring into the Agilent 8753C does not work in revision 4.11. Using this command causes incorrect data and annotations to be displayed, and may lock up the system.

Note: See the 08753-60207 phase lock board warning in version 4.02 above.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  • All previous firmware revisions had a bug that would freeze the display when the analyzer was in dual channel mode where one of the channel formats was a Smith chart with at least one active marker. This problem usually occurred when changing s-parameters of formats and could be remedied by pressing the PRESET key.

  9. Modified sampler cal freqs for third harmonic.
  10. Power trip in cavity osc test (54). Changed prompt to user to use the low pass filter rather than a cable. Set the high power AFTER the freq is set to the filter stop band.

Firmware Enhancements

  1. Mods to internal memory directory text to differentiate user preset and preset states.
  2. The REF VALUE key is now aliased to SCALE/DIV when in polar and smith chart formats.
Firmware Problems Fixed
  1. LIST VALUES then RENAME shows list characters in the title.
  2. TTL input isn't working.
  3. Fixes interpretation/encoding of null timestamp (DOS only).
  4. Free number of Bytes in directory is not updating.
  5. DOS label deleted with DELETE ALL files command.
  6. DOS label does not show when created on a PC.
  7. When the down step key is used in polar format, the reference value goes to 0.
  8. While in user-preset mode, user can't recall factory preset from the list.
  9. Re-naming the PRESET register messes up save/recall display.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  1. SAVE STATE to disk while creating sequence uses wrong file name.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

Firmware Enhancements

  1. Added the capability to print to a DeskJet 540 printer. This added a new softkey under [PRNTR TYPE], [PRNTYP540].
  2. Recall speed improvement
  3. The INITIALIZING DISK message chagned, it now reads "INITIALIZING DOS DISK" (or LIF), depending on the format selected.
  4. Updated the 8753 and 8752 SELL command to work with post 5.00 revisions. The current 875x can now generate and receive instrument learn strings from 5.00, 5.20 and 5.24 (for the 8753)and from 5.10, 5.20, and 5.26 (for the 8752).
Firmware Problems Fixed

  6. HP8752C recomputes factory cal. when changing channels from channel 2 to 1.
  7. Admittance Smith chart, fixed marker value incorrect after recall.
  8. Added save/recall support of TEST SET I/O values. Saving instrument state to DISK use to destroy these values.
  9. Fixed a number of problems related to remote/local transitions of the HP-IB bus.
  10. LOCAL 7 releases REN and the last command is not executed.
  11. DONM hpib code lost if bus set to local too soon afterwards.
  12. Using numeric keypad afterarray dump in instr (over hpib)hangs instr.
  13. Clearing the error queue does not remove error message in the display.
  14. Fixed the setting of the FIXED MARKER STIMULUS "x-axis" value (previously it incorrectly limited values in TIME DOMAIN and other domain modes).
  15. Fixed the following source correction defects:
    • Sign error in Sq Law/Lin DAC routine in Service Test 47.
    • Square Law/Lin window set to tight in Source Correction.

  2. Fixed defect described as "CS followed by RS HPGL commands prevent analyzer from sweeping."

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  1. Single segment frequency list state does not sweep on recall.
  2. Update arrow works incorrectly for fast sweeps in list mode.
  3. Added fixes to eliminate power spikes due to attempting to reset power during RF blanking and when restoring RF. Not blanking the RF when setting power if in the same power range.
  4. Start freq for all confidence tests now 300 kHz.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  1. Saving instrument state with interpolated cal causes corrupt state.
  2. Full two port cal corrupted by save and recall from DOS disk.

For Special Handling ONLY.
There is NO PCO or LCN associated with this release.
(The tape archive will be retained by the R&D FW team for the time being until other logistical details can be thought/worked out. JULY 1996)

Firmware Enhancements

  1. Added MuRata code (conditional) for the 8752 to use the TTL bits 0-2 to note limit test output status. Murata Code is enabled ONLY through cpp flag MURATA.
  2. Added a new limit test routine to speed up limit testing.
Firmware Problems Fixed
There were no problems fixed for this version of firmware.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  • This was noted by an HPED customer using the 8753D with the IC-CAP program.
    When in CW, different power levels on foward and reverse, and two port error correction on, the measurement was incorrect for the forward parameters by the power difference between forward and reverse.

Firmware Enhancements
There were no enhancements for this version of firmware.

Firmware Problems Fixed

  1. Corrected phase lock failure errors for specific frequency ranges as noted by production engineering.
  2. Save/recall used to go through attenuator 0 value and then set desired attenuation. This is now corrected to set the new attenuation only for the change needed.
  3. Fixed ATM 875x.683 (could not display more than 4 options on the power up option string).
  4. Agilent 8753D ONLY (not for Opt 011)
    Switching from port 1 to port 2 when they have different power levels (PORT POWER UNCOUPLED) causes the higher power to appear on the lower power port momentarily. This is now fixed so that:
    • high -> low : lower power first, then throw transfer switch
    • low -> high: throw transfer switch first, then raise power
