If you have dirty pads usually your loss will roll off at lower frequencies and then normalize at higher bands , this is because the dirt in essence is a series capacitor creating a high pass

Yes, cables called "null modem" tend to have pins 2 and 3 swapped, IIRC.? Apparently you don't want one of those.? Those in this group more familiar with datacom than I am can expand on this.?

In the 8340/41 the output power indicator is measuring power before the attenuator so will indicated “requested” power, not actual output power. Band 0 is 10 MHz - 2.3 GHz, the swept LO is mixed

Hi Jim Adney, I have a 200CD Ser.605- working on my bench and a few days ago in the middle of another repair my 200CD signal failed, how is it possible!! it was completely silent, it was left to wait

Hi all My HP 8341B sweeper looks like output down 10dbm~13dbm from requested level output...measured on a Boonton 4200 power meter know good. I rarely use it above 1Ghz... IIRC <2Ghz is band 0 didnt

Ordered a 6ft cable, will report back with my results. I have tried slow sweep, less points, zero span. No luck.

IIRC, Metamagnetics considers the 4 dB the insertion loss.? In an interference-limited receiver, that would probably be acceptable.JimSent from my T-Mobile 4G LTE Device

Hi Jim: Interesting.? It seems that the weak (desired) signal is attenuated about 4dB while the strong signal is knocked down to the limiting level.? See:

Seems ike you could mitigate the problem by slowing the sweep down. Cheers! Bruce Quoting Lothar baier <Lothar@...>:

This just FYI ! I talked to a friend of mine this morning who was working as a test engineer at raytheon for 20 years , they used 8510 systems and in some applications had to use the testsets in a

Switching the input coupling to GND makes no difference as far as I can tell. Also, does anybody have any recommendations for mosfets to use for a replacement circuit? or important specs at least.

Just made a few calls to Keysight and 1460-1311 grounding clip is definitely not orderable. I have the dimensions of the clip so I will try and manufacture a clip out of BeCu sheet metal. Thanks,

Hi everyone and sorry for the OT, but this group has the best chances to help in this case. Does anyone happen to have the Leader LVG-1600 manual? Even only the user manual would greatly help. Thanks

Ok Yves, makes sense now. My figures are a bit different, but looks ok overall. Thanks for your helpful data again.

Regardless it is best practice to keep cable lengths at a minimum, DB25 cables retail from $5 to $20 depending on make and length so its not cost prohibitive to aquire a short cable

Thanks - Excellent, now he can test his cable. Cheers! Bruce Quoting Lothar baier <Lothar@...>:

Pin 4 Pin 10 Pin 11 Pin 17 Wired straight through ! I am using a DB25 cable from Amazon 3ft works flawless Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows Sent: Wednesday,

If you know the cable connections please POST it to the board. That way, he can check his cable and "fix" it if necessary. BTW - IS the cable straight through? If so, which conductors are needed?
