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 |

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.

Max, About the meters for the HP 606... I have the manual for the 606B, which lists the meters in the parts list. M1 (Percent Modulation) is a 200uA movement, part number 1120-0075 (the parts list identifies it as a 200ma movement). M2 (RF Output) is as a 100uA, part number 1120-0074 (listed as a 100ma movement). Cheers, Dave M |

That helps. Thank you. Finding the modulation meter would be nice but if I found the RF meter I could shunt it and change the scale. If someone could tell me where to find a negative resistor I could use the 608 modulation meter and shunt it to make a 50 uA meter. That's a joke yall.
