When I measure a 1uH inductor at 100kHz, the Q measurement jumps all over the place. How can I get an average?  

Hi , I have designed the output matching with CPWG(cpw with ground) line and L,C component. schematic.png EM1_2.png EM2_2.png EMcosim.png But the result of EM-cosimulation looks strange and different from the result  of schematic. (S(37,37) is for schematic, S(39,39) is for EM cosimulation) result.png Can someone give me any advice

HP8591E  drift at zero span  Hi everybody how are you? As the title,  is the problem that I found in my recently acquired SA Done all self calibration procedure. TG calibration Amplitude Calibration Frequency Calibration       Setting the TG to 10.000 Mhz at zero span   Counter show at list 7.61 Khz

I just purchased a U1733C, LCR meter and for the most part, it works fine.  However, I'm questioning the accuracy.  It reads OK with electrolytic capacitors up to 1uF but with values higher than that, the accuracy degrades.   The meter settings are, 100hz frequency, series capacitance and before the measurements, I calibrate
