We still are using the HP 8673D signal generators and have been calibrating / adjusting them for years now using the HP 11726-1000A Cassette and HP 85D controller.
Our HP 85D controller went wrong several months ago and we are unable to get any spares (not surprisingly). Did Agilent (or anyone else) convert the HP 8673D adjustment program on the HP 11726-1000A Cassette to any other media since we can no longer read the cassette to run it in HP (HT) Basic……
If not does anyone have a manual procedure for the adjustment of these generators?
It is very unlikely any effort was put in to migrating old adjustment software into any other format.
We checked with the Roseville Service Center. On a best effort basis they can still do Performance Tests, Repair and do Adjustments of the 8673D’s. Most of the adjustments on the 73D are manual though some tests dealing with Power Level Accuracy are automated.
The best we can offer on this old product is the possibility that the Service Center might be able to Repair and provide Adjustments. And, provide Performance Verification if that is all that is needed. In any of these cases, you should request a Tech Eval first to determine if what needs to be done on this unit can be supported by the Service Center.
Just had a chat with the guys who were carrying out the adjustment on these units, they have just received a 8673D back from the USAF, AFPSL via Roseville, it took over 10 months, due mainly to the fact we are currently stationed in the Middle East.
What they have been doing is only sending out the units that required repair due to the lead time, as they can no longer adjust the power level on the units they end up sending the 8673D’s back to the US for minor adjustments and not repair.
The guys said they have tried manually adjusting the power level since the HP85 went out of commission, with some small success, but were far quicker and more successful using the old software.
Does a program listing for the 11726-10004 (in whole or just the leveling part) exist so that I could spend time converting it to run in HP/HT Basic so this does not effect the down time on these old generators.
