Matti, Just to save Jim the time to look up that error code again here below is what he sent when I was working on my unit. Also some test codes from Tracey. Dex Thank you very much Jim for SPM-19 in
Thank you very much Jim for SPM-19 input impedance info. Sometimes I get error message 1--202, which disappears when I change attenuatorīs value. Could you please check whether the manual can tell so
Dear Matti, The manual says " > 10kohm//60pF" in the infinite impedance position. The additional attenuation caused by connecting this input across a 75 ohm system is specified as less than 0.05dB at
Dear Jim, I have SPM-19 too but without any manuals. Could you plase check what kind of input impedance is in "unbal 75" but selected without termination (infinite). Instrument works great if not gon
Jim, Thanks for the info. This SPM-19 does have the audio output circuit which I suspect should produce a 1750 Hz audio tone when the unit is tuned to an exact frequency. I believe that was the stand
Dear Dex, There are only 2 frequency conversions in the SPM19 - one to the 40MHz first IF (which is what the 40-65MHz LO signal does), and the second to the 10kHz final IF. You could include a third
I have a Wandel-Goltermann SPM-19 I would like to dedicate to the Spec Lab plotting duties. This unit has had a receive problem every since I got it over ten years ago. So I have primarily used it as
