I have an 8590A and it didn't have the calibration numbers in for the 20-db attenuator flatness or the flatness calibration data. I manually entered this with just zeros to get the acquisition to display properly. However now I am not able to perform calibration as it reports no calibration signal.
Looking through the manual downloaded from Artekmedia under "Generating New Calibration Data" that "This section of this chapter is supplied in the accompanying change sheet." Unfortunately I don't have this change sheet nor am I able to find it anywhere. By any chance does anyone happen to have this change sheet or could tell me how to generate the proper attenuator and flatness calibrations?
Hopefully entering proper calibration data would allow it to properly detect the calibration signal. I have connected it to my oscilloscope so there is a calibration signal being generated.
Thanks!

First a couple of questions.
Do you have the support man ?
Did you see aspike on the most left side of the screen after power up ?
Was/is the cal signal of 300 MHz on the screen seen before altering the factors?
Did you use the specialcodes for entering new value ?
Only the 20 dB error factor need to be entered. The analyser will correct the actual value by itself, if the Cal sig. is available !
This is seen on the display p 4-17 CAL (MORE) soft key DISPLAY CAL DATA eg. Artek Support man. page 4-18 .
When the cal sig 300MHz is not displayed the possibility excist the first mixer is not working, both diodes are defect.
Adam I'll help you on track!
