70902A spectrum analyzer IF module RESOLUTION BANDWIDTH problems
Hello,
I am trying to fix a 71100A spectrum analyzer and I'm stuck. It passes the "analyzer test" built into the firmware but does not pass calibration of the resolution bandwidth for some of the bandwidth filters (in the 70902A IF module). The problen is easily seen in the shape of the curve from the calibrator, which for three of the filters does not look like it should. If you take a look at you will see that: * 10 Hz: Looks like if it was composed of two filters in series not aligned to the same center frequency. Peak amplitude 8 dB down. * 30 Hz: Almost right but again not 100% symmetric. Peak amplitude OK. * 100 Hz: Seems nice to me. * 300 Hz: Just A bit asymmetric * 1.00 kHz: Ugly, centered but no simmetry. Peak amplitude OK. * 3.00 kHz: Ugliest, a complete mess. Peak amplitude 13dB up. * 30.0 kHz: Looks nice. * 100 kHz: Strange shape, convex skirts instead of concave (??) * 300 kHz: Strange shape, convex skirts instead of concave (??) The first error ( 2023 , Illegal Cal Signal ) appears when the 3.0 kHz test is done. The last one ( 6011 , RBW hardware error ) appears after the last one, which is the 10Hz test. I have the Component Level Information Package (from ARTEKMANUALS) for the module, and it shows there are (among other), 9 filter stages: LC1 > LC2 > XTAL1 > XTAL2 > XTAL3 > XTAL4 > XTAL5 > LC3 > LC4 Most of the stages have a bandwidth and center control pot/cap, some also a symmetry control. I tweaked them and could not see any significant difference in the ones that don't look nice so I carefully left them all where they were. There are also "SHORT" LEDs on each filter stage, I believe to signal which stages are being bypassed. What I do not understand is why the LC1, LC2, LC3 and LC4 LEDs are never ON and the XTAL1, XTAL2, XTAL3, XTAL4 and XTAL5 are either ON of OFF, all at the same time. From 10K up they are all ON and from 3K and down they are all OFF. I was expecting some kind of weighted switching to get the desired filter bandwidth, so I could find and repair the stage that was failing, but it does not seem to be that easy. Since it is possible to have continuos bandwidth control, some of the stages are probably not as simple as I thought. Appart from some of the trim caps being stuck, there was no physical damage that I could find. Does anyone know how the filter stages work? Suggestions to try? Thank you and Merry xmas to you all.

Re: FS: Percent Modulation meter for HP 608 (?) signal generators
Oops? I looked up the meters in the 608D manual and I find that the two are not identical. The RF level is 50 uA while the modulation is 1 mA. Unfortunately I need the RF level for the 608. In the case of the 606 the PDF of the manual I have is not very clear and I couldn't find the meter listing. I think they are both 200 uA meter movements. I had to shunt the 100 uA meter I kluged in to be able to calibrate it.

Re: HP-608A Repair

I think the oscillator is okay but I will take another look. If it's weak I'd expect no output on some frequencies, which isn't happening.

FS: Percent Modulation meter for HP 608 (?) signal generators
Hello--
In case anyone needs a replacement, I'm offering FS a NOS (new-old-stock) "Percent Modulation" meter, HP p/n 1120-0397-1, 1 mA full-scale movement. This meter bears a corporate calibration sticker that seals the meter's adjustment screw, but the date-of-calibration code is not obvious. IIRC, this meter is an exact replacement for the percentage modulation meters used in HP's 608-C (and possibly other 608-family?) signal generators; if that's incorrect, please let me know. I'm asking $10.00 plus USPS postage; I honor PayPal and welcome questions. Thanks, and 73-- Brad AA1IP |

HP Oldies.
I am looking for a couple of HP oldies. The 260A Q meter and the 250A RX meter. I can't find any on eBay. These two instruments were carried over from Boonton when HP bought them out.

Some years ago, I was at a ham flea-market and found a nice Tek scope cart. I asked how much, and was told that I had to take "this" with it, and it was $25. "This" was an HP608E. So I took it. The 608 works, except there is something flaky in the attenuator. (I really don't understand that, since the attenuator depends on physics, not resistors or pots, but anyway. . . . --doug, WA2SAY The sliding part of the attenuator has a couple of 53 ohm resistors and a variable capacitor in it. It may or may not be possible to get the thing apart to replace them. In any case it would be a lot of work. Regards. Max. K 4 O DS. Email: max@...

Re: HP-608A Repair
What a remarkable coincidence. I have just come back on the list after being on no mail for some time. Most of you are working on somewhat newer things than I am. I just finished putting a 606B and a 608D back into operation. I have run into a sticking meter problem with both. I was not able to use the modulation meter in the 606 and had to kluge a 100 microamp meter in its place. If anyone has either the modulation or RF level meter I have saved the scale so I could use it. On the 608 the RF Level meter sticks above the set point which makes it a lower priority but if anyone has one lying around it would be nice to have the full range capability. As with the 606, both meters are identical so if you have a modulation meter I can just switch the scales and be all set.

For the gentleman named Dennis Klipa I have quite a lot of experience with tube gear and I could probably fix it if none of the parts made of unobtainium are defective. I have a source for the pencil triodes although they aren't cheep. The shipping on it would be a bear though. I live in Bowling Green Kentucky. Regards. Max. K 4 O DS. Email: max@...
