Gang,
I have found a couple of NOS HP CRTs and I can find very
little info on them. I suspect they are from old oscilloscopes. They are
5083-5072 and HAR 81149. Does anyone know what equipment used
them?
Thanks!

Re: Rear Cables for HP-8568B SA & Display Unit Needed
Gah, you can pay more for the cables than the SA.
It is possible to make them up yourself, if a bit tedious. The
bus cable is not straight through, but it is documented in the
service manual.
The price for the connectors for the coax cable alone can hit
$70-80 or more though. So GLK's price on those is pretty good.
The best price I ever found for the coax cable was a kit someone
was offering on ebay for $50. That's been a while though.
I can make up bus cables for signifantly less than GLK, but I currently
lack a good screw solution for the centronics side of the cable.
They do show up on ebay once in a while. They don't last long if they're
priced anywhere reasonable.

I recently purchased an HP-8568B 100 Hz to 1.5 GHz SA with matching display and am very excited about it. But unfortunately the two required interconnecting cables for the rear connections were not included.
I believe the HP part numbers are:
85662-60093 (coax interconnect), and
85662-60094 (Bus interconnect)
I was wondering if anyone had a pair of these cables they could part with so I could see if my new baby works? I would be happy to pay for them plus any shipping. Thank you !

I am working on an 85101B Display Processor for use on HP 8510 Network Analyzer.
The Focus Gate Amp uses two of these 1854-0404 SI NPN @ Q13, Q14 both FUBAR.
Before I purchase these on line, if someone has spares for purchase, please contact off list.
I appreciate the help, with those replaced I should be in like Flint.

Re: HP 83592B hangs 8350B sweeper
Thanks Ed, I have sorted out a few things. The drawings in the manual of A9 are back view but can be mistaken for front views because the transistors are drawn that way. This makes the schematic correct with Q1 the YIG tuning coil driver (see A8 description), Q2 the SYTM (Switched YIG Tuned Multiplier) driver (see A7 SYTM Driver), and Q3 the 78H05 regulator. I checked the collector voltages of ?Q1(pin2) and Q2(pin10 on motherboard) ? Select Freq???????? Actual freq???????? pin 2????????????????????? pin 10 50 MHz???????????????? 50.4??????????????????????? +5.63v?????????????????? +15.98v 100 MHz?????????????? 101???????????????????????? +5.44???????????????????? +15.98 500 MHz?????????????? 503???????????????????????? +3.92???????????????????? +15.98 1 GHz??????????????????? 1.006???????????????????? +2.029?????????????????? +15.97 2 GHz??????????????????? 2.012???????????????????? -1.77????????????????????? +15.98 3 GHz??????????????????? 3.002???????????????????? +8.84???????????????????? +15.99 4 GHz??????????????????? 4.007???????????????????? +5.05???????????????????? +15.16 5 GHz??????????????????? 5.013???????????????????? +1.254?????????????????? +14.34 12 GHz????????????????? 12.026?????????????????? -2.53????????????????????? +8.52 13 GHz????????????????? 13.031?????????????????? -4.42????????????????????? +7.70 14 GHz????????????????? no O/P????????????????? +2.56???????????????????? +6.91 ? They seem reasonable, but maybe not the SYTM (Q2 pin 10). The bands change at 2.4, 7.0, and 13.5. It seems strange the frequencies are close up to 13 GHz. A rough calculation has each transistor dissipating 1 to 2 watts but the regulator could be higher with 7 volts across it, so 7 to 20 watts depending on the current. I cannot measure the current of the 5v supply without cutting traces and there is no wire to hang a DC current meter onto. The heatsink gets very hot at any CW frequency. I don¡¯t think the unreg 5v should be as high as the 12v I measure. The top cover screws onto the top of the heatsink and maybe is needed to dissipate the heat, another 24 sq in of metal close to the 8350B top lid! I¡¯m going to drop this investigation for now. I don¡¯t think the lock up is due to a power supply, I have checked them all. I can get it running in CW but as soon as I press START the 8350B locks up with no display, no error, and no response to buttons. I need to switch my attention to the sweep circuits before I can calibrate anything. I know this has been meddled with because the top cover is missing and an SMA connector was loose. Peter. ? ? ?

Subject: RE: [hp_agilent_equipment] HP 83592B hangs 8350B sweeper? ? I just noticed the original posting - it looks like the frequency is reasonably close, but amplitude is way off. Depending on the band (N), it could just be that alignment is needed, once the basic problem is fixed.
To get enough output power available for leveling, the YTO and YTM tuning have to be properly set up to track each other through the entire range of coverage. It could be that someone before had grossly misadjusted it while trying to fix it. Once you figure out the setting/overload problem, the rest should be OK after adjustment.
If the fundamental band around 2-7 GHz (N=1) is OK, but the higher ones (N=2 or 3) are not, it could be a problem with the YTM or power amp.

Re: HP 83592B hangs 8350B sweeper
I agree - YIG coil loads on the supply may be dragging it down. But first, does it produce the right frequency at lower settings where the problem doesn't show? This would confirm that the coil drive is at least OK.
Also, as I recall, there are two YIG device coils to drive - the oscillator, which should go around 2-6 or 2-7 GHz, and the YIG-tuned multiplier (YTM) filter coil. Both go up with frequency, but the oscillator will be periodic in tuning, repeating its range while the multiplication factor "N" changes with bands. The YTM coil only goes up and up, probably taking the bulk of the current.
There's also a power amplifier to drive the YTM - it may be juiced up another notch as N is increased. 13.5 GHz may be where N changes from 2 to 3.

Re: HP 85047A (S-param test set) with loose Port1
The test sets were designed this way on purpose.? There are test fixtures with a fixed spacing that are designed to mate with the front panel of the 85047, and one port had to have some slop so that slight variations in manufacturing would not prevent proper mating.? There are several other products like this with a "floating" design.

Re: HP 83592B hangs 8350B sweeper
Good thought Dave, this is where I¡¯m headed next but it is difficult without a proper schematic. My manual (download) has a whole lot of extra stuff at the end of the manual that I did not print. There may be something in there. Peter. ?

To me this further suggests a power supply problem. As you increase
the YIG coil current by calling for higher frequencies, one or more of
Q1/Q2/Q3 is heating up too much, and probably dragging one of the power
supplies down. How do the rails look when you go up into that frequency
range?
