Click to view contentHello. Just picked up a used E4407B (needs help) and wondering what's up with the strange results on the hardware screen.    Not sure if HW ID 226 is real or not.   Anyone have a list of these ID codes? The unit aligns fine (no errors at least) but it does say "Frequency Reference Error" sometimes... intermittently. Not sure what that means… (Show more)

Hi ,   I am trying to use this SCPI command ":CALCulate:DATA?"  in Python but I am facing issue with ValueError: Could not find **** sign (#) indicating the start of the block.   Also If possible can you please share the sample code for Python.   Regards, Dhanabal.K

Picked up an 8594E relatively cheap (it works fine) but it doesn't have narrow RBW filter, FAST ADC (for analog + display capability) and AM/FM demod options. It came with the TG and option 119 (which is easy to remove). Option 151/160 chews up remaining expansion card cage slots (2) and I need to free up room to install the other 3 cards. Looking… (Show more)

I have an old E4402B that hasn't been used for about a year and its internal battery died since it was last used.  I've replaced the battery and now it keeps time, the settings, and it knows its been aligned now but I seem to have lost the bluetooth measurement application (option 228) due to the battery dying.   The measurement keys no longer… (Show more)

Hi,   We are using PSA series spectrum analyzers in our MMIC validation setup. I had the following question on the use of a noise marker.   I would like to measure the noise density(dBm/Hz). Would there be a difference in the measurement two measurement scenarios listed below?    I turn on the normal marker with an average setting of say 50… (Show more)

We have "N9344C" spectrum analyzer and as per datasheet frequency range is 1MHz to 20 GHz. Can I use this spectrum analyzer for the input frequency of "100KHz to 1MHz"?

The HSA user guide says that using a log-frequency scale is useful for filter analysis: "When measuring filter characteristics, it is useful to look at the stimulus response over a wide frequency range. Setting the analyzer x- axis (frequency) to display logarithmically provides this function. The following example uses the tracking generator to… (Show more)

Hi,   I have the following question with regards to real time. If I work with my N9020B in normal spectrum analyzer mode, I can either have the traditional swept mode or alternatively, I can move to FFT sweep to increase measurement time.   If I understand correctly FFT is also the core also for Real Time Analysis gap free, so if I change to… (Show more)

We are using a N9030A PXA signal analyzer with the EMI receiver option to run CISPR radiated emissions. According to everything i have read, it says this device is for pre-compliance testing. What is it that makes it pre-compliance only? Is there an option that makes it usable for compliance testing? I have looked for clarification and have not… (Show more)
