• Original factory EPROM images for an IFR-1500, Serial No. 1567:
• Version 1.6 #1  U10 CS: DDDE  (MBM2764-30)
• Version 1.6 #2  U11 CS: 637B  (MBM2764-30)

• Version 1.6 #4  U?? CS: B540  (MBM2764-30)  (It's not labeled for some reason, below EPROM #2.)
• 3263-2320-100  U42 CS: AD22  (M2732A)  (Unknown use.)
• Tone #1  U46 CS: ????  (M2716)  (On the Dual-Tone Generator board.)
• Tone #2  U28 CS: FF80  (M2716)  (On the Dual-Tone Generator board.)
• Common failure for "no RF output" on the IFR-1500 is a shorted tantalum capacitor (horizontal, yellow in color) in the Output Amplifier module (it's a pain to get at).  This will also blow out series inductors in the module's +12 VDC line(s) and can even burn out the SJE1426 PNP pass transistor on the Audio Demod plug-in board.  Replace the SJE1426 with BD140, MJE350, or TIP32.

A105 Microprocessor - 2020195-E U13 4k x 8 PROM (TMS2532), Basic 2 650000x-01 U14 2k x 8 PROM (TMS2516), Expansion U15 4k x 8 PROM (TMS2532), Basic 4 650000x-03 U16 2k x 8 PROM (TMS2516), Basic 1/Option 640000x-01 U17 4k x 8 PROM (TMS2532), Basic 3 650000x-02 U19 2k x 8 PROM (TMS2516), GPIB/Option 640000x-03 U19 (Alt) 2k x 8 PROM (TMS2516), BCD Remote/Expansion 640000x-04 U20 2k x 8 PROM (TMS2516), Expansion 640000x-02 (Note that on some models these IC locations are different!) A107 Gate Generator - 2020197-01/02-L The POWER METER PROM (Option 02 only) contains a logic comparator (U21), a 2k X 8 PROM (U20), and a bus driver (U19). The logic comparator is connected to the microprocessor address bus, and is configured to decode the 2k address range from 0x4000 to 0x47FF. The comparator output drives the chip select of the PROM, and the bus driver. The PROM contains the Power Meter program as well as the power correction factors. Bus driver U19 is used as a buffer for driving the microprocessor data bus. U19 Octal Buffer 74LS244 U20 PROM TMS2516 U21 6-bit Comparator DM8136 A109 Band 2 Converter - 2020139 Provision has been made on this assembly for a set of jumpers that will let the microprocessor know when it has the components required for a 548A (26.5 GHz) counter, and if it has an extended frequency option (Option 06). These jumpers are read by the microprocessor when the counter is turned on, and will select microcode which is applicable only when those options are available. A jumper from E1 to E3 (from pins 8 and 9 on the PIA U2) indicate that this is a 548A counter. A jumper from E2 to E4 indicates that Option 06 (Band 4) has been installed.

• HP 8563A - 920504 ROMs  For Serial No. 3337A02655 with Options 026 and H51  (AMD 27C020)
• I believe the H51 option (EMI testing, included two HP11970X external mixers) is a hardware/software option which turns the device into an 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.

A.14.06 Firmware Upgrade

These disk images were made using RawWrite from a real floppy drive in a real computer running real Windows XP.  It should help fix the "blank white screen" when doing a firmware update (it doesn't like floppies formatted on modern Windows systems).  Use RawWrite to write these raw disk images to nine new floppies:

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.
