• HP 8563A - 920504 ROMs  For Serial No. 3337A02655 with Options 026 and H51  (AMD 27C020)
• I believe the H51 option (EMI testing?) is a hardware/software option which turns the device into a AN/USM-489A.
• For proper Option 026 (26.5 GHz) operating, you'll need the following hardware upgrades:
• RF Attenuator: 5086-7796 (26.5 GHz)  (Stock 22 GHz version is 5086-7783)
• YTF: 5086-7850 (26.5 GHz)  (Stock 22 GHz 0955-02777)
• RF Switch: 3106-0032 (26.5 GHz)  (Stock 22 GHz 3106-0022)
• It will work without the hardware upgrades (and re-calibration) but with high insertion loss.

• Sirenza SHF-0189  This is the device labeled "H1" or "M11X" on the RF output board which fails giving the "UNLEVELED" error message.  (Biasing App. Note)

It is also easy to enable full output frequency range (4 GHz) of these old obsoleted ESG generators, using simple GPIB commands:
   SERV:PRODUCTION:CAL:BEGIN;
   SERV:PRODUCTION:CAL 165,2,4000000000.000000;
   SERV:PRODUCTION:CAL:END;
   SERV:PRODUCTION:CAL:STORE 165;
   SERV:PRODUCTION:CAL:PUP;
After instrument is rebooted I can output higher frequency out of the RF port, with drawback of the reduced output power stability.
* The cal data is wiped and you'll need to recal.
* No risk, if you save the content of U106 and U107 first, everything is stored in them, so if you should mess things up, just flash the original content again.

* FYI, these units also have a failure mode in the DC bias of the Burst Modulator resulting in zero output to the final mixer stage.
  The simple solution is to rebias using a 20 kohm jumper resistor in the previous stage or to jumper all the burst PIN diodes and defeat 
  the burst.  Problem solved by a 20 kohm resistor jumper to feed the Burst Modulator from the ALC mod PIN bias.  Pics and details etc. on EEVBlog.
