I am using an E4443A Spectrum Analyser and interfacing with it via SCPI commands using MatLab. I am trying to get a trace from the instrument similarly to what is returned by the 'trace:data? trace1' SCPI command, but I would like that trace to contain data reported by the 'Marker Noise' function. My current process is as follows: Turn on… (Show more)

Blown Analyzer Port 1 on Four Port Analyzer, Can I use another pair of ports?

I am using a switch in my test setup with some limiters on ports 1 & 2 of the analyzer. The limiters do not always clamp in time, and in this case port 1 was blown out on the analyzer (verified by turning correction off and connecting a load to the port and comparing against known data). My question is whether I can use another set of ports,… (Show more)

Hello, If Ports 1, 3 and 4 receivers are good then you should OK to use any combination of these as your 2-ports. The E5071C as a 4-port unit has eight receivers: References 1 - 2 - 3 - 4 (by port number) and Measurement receivers A - B - C - D (for ports 1 - 2 - 3 - 4 respectively). If you save Touchstone files then the numeric…

I am using E5071C agilent technologies. I also found these commands, but it's not working. Usually what command will you give to fix the marker at specific frequency.

Unable to run data logger with error "ASRL1::INSTR : Operation terminated due to a timeout"

Hi, Good day. I had been using a Benchlink data logger 3 connected to a PC and it was used with a thermocouple for temperature reading. Recently when I tried to run it, the data logger response was very slow and end up with a error message pop up "ASRL1::INSTR : Operation terminated due to a timeout" I had try to reboot the PC and change… (Show more)

Hi, I tested my 34970A with DATAlogger 3 at 9600bps without problem. If I used this configuration with RS232 straight cable instead off a null modem cable (cross over), I have the error message "ASRL1::INSTR : Operation terminated due to a timeout". Check your rs232 cable, you need null-modem (cross-over) cable. Yves

Multi-site function support for M980xA

The on-line help Rev A.13.70 (M980xA/P500xA) Rev A.13.10 (P937xA) Rev A.12.60.xx (M9485A/M937xA) - 2-Jul-2019 states that the M980xA doesn't support the multi-site function. Is this because the M980xA is new and the "firmware" hasn't been updated yet for the support or is there some other reason? PXIe VNA Multisite Note: M980xA does not… (Show more)

Gating function in PLTS to observe insertion loss

Hi Keysight community, May I ask if it is possible to perform PLTS gating on a measured TDR plot TDD11 at the SMA launch region and observe SDD21 for the rest of the interconnect along the thru path? I read up some application material but many only describe using gating approach to observe just the reflections. Any insight will be much… (Show more)

HP 85047A test set coupler (5086-7489) - disassembly

HP 85047A contains HP 5086-7489 test port coupler which grossly fails simple directivity test (terminate with known-good APC-7 50 ohm load, and almost all source drive signal appears on the coupled port save for a notch/dip at mid-span. As the history of the test set is not known, abuse is suspected. Visual inspection inside the RF coupler… (Show more)

Don't try to scrape it off. Just measure the resistance across it. Then add an external resistor in parallel to get close to 265. the substrate is pretty fragile and if you break it, you are out of luck.

eye closure under Jitter mode, but not eye mode

Hi, I recently try to do jitter measurement on DCA-X module 86108 for a 53G PAM4 signal. I have a deembedding function to remove a S4P file, and followed by a CTLE transfer function that applies 4dB peaking. In order to use those, I had pattern locked to PRBS13. Under Eye mode, I see that the eye is pretty open with 60+ mV eye height and… (Show more)
