Hi,   I have replaced CPU board in my 8753E, I have also moved the U408 chip from old board to new (is it contain calibration parametres?). Now when I start the analzyer there is no errors/fails but I have recognized that led UNLK is blinking while sweep the frequency but there is no error on the display. When I have changed sweep time to 20s … (Show more)

Dear All,   I have been reading Hong's "Microstrip Filters for RF/microwave applications" recently. In his book, he mentioned many times to do the measurement by inserting an electric/magnetic wall at the symmetrical plane. But I do not know how to do it in the simulator(I use ADS, layout editor, not schematic editor). The reason I want to insert… (Show more)

Acquired a E8357A with 266MHz CPU, 10GB HD and 128K RAM running Win 2000. It seems to have all the latest FW and SW updates. I ordered a Micron MT16LSDF3264HG-10EG4 512K RAM for upgrade. I assume this will be compatible.    What is the preferred method to "clone" the HD as a backup? As a test, I used an old Win 2000 PC and via Acronis cloned it's… (Show more)

Before calibration, Setting to "new user calset"                       pref = (AgilentPNA835x.IPreferences17) pna.Preferences;           pref.RemoteCalStoragePreference = AgilentPNA835x.NARemoteCalStoragePreference.naPreferNewUserCalSet; After calibration, It generates an empty "calset_1" file,  and the real calset is still stored in CH1_CALREG .… (Show more)

PNA firmware A10.65.01, During and after NF Cal process (Scalar Method, Noise Receiver, Power Meter for Rx Characterization), if Port 2 power > -10dBm, "Unleveled, Source1, out 2" warning message pops-up , If increasing Port 2 power > -5dBm, extra "Warning: Receiver R2 overload" pops-up no matter Port 2 Receiver Attenuator sets. This happens only… (Show more)

Hello everyone, I am developing a system based on interferometry (diagram attached) and I don't know how to properly calibrate the system. I have a PNA 5242A and a Ecal module (N4691-60004). I had performed a 2 full port calibration before hybrid coupler but the cable contribution before DUT is quite strong, so I would like to remove it. I was… (Show more)

Hello, my lab is using a PNA N5225A with electronic calibration kits N4433A and N4692-60001. I am trying to make S-11 measurements in the frequency range 400-1300 MHz for unmatched, electrically small antennas which have will have a very high reflection coefficient at the input (close to, but less than 0 dB). In order to see the S-11 value, I… (Show more)

While calibrating NF at:  Calibration Method: "Scalar Noise method"; Receiver Characterization: "Use Power Meter";  DUT Connectors: APC 3.5 female; Ca kits: N4691-6009 Guided Cal 1st step: "Connect N4691-6009 to port1 and 2"  Done                     2nd step:   "Connect Port1 to 2"     PNA breaks down as attached screenshot. PNA firmware:… (Show more)

I noticed, that one of our 85130F testport adapter set NMD2.4-3.5 female adapter (85130-60011) has loosed body from the center. See attached picture and red area where connector has loosed. I managed to tight it with fingers and Pin-depth looks still normal, but I still have unsecure feeling to use that adapter during calibration. Can Keysight… (Show more)

My PNA 5321A has had an error splashed across the display for a few months - "Unleveled source 1, out 1".  I've finally gotten around to "clearing" the error, using the helpful info on this forum.  I found these two to be quite useful: https://community.keysight.com/thread/4245 https://community.keysight.com/message/69834   I tried changing my… (Show more)
