How do I setup my ESA-E Series Spectrum Analyzer for narrowband Noise Figure measurements?
- Select and attach your noise source
- Press [Mode] and select {noise figure}
- If DUT is a frequency converting device go to [Mode Setup] and configure
- Press [Frequency] key and select {start freq} and {stop freq}
- Select the number of {points} to display on the screen - default will show "eleven"
- Set the resolution bandwidth a level lower than the bandwidth of your narrowband DUT, via [BW/Avg] {res BW}
- Decide whether you are going to do a standard swept measurement, or for faster measurements use the frequency list mode to just measure the number of points needed to acquire the necessary results.
- Using the measurement key [meas set up] enter the {Avg Number} required
- If not using SNS set the {Tcold} temperature unless a constant 290 K can be guaranteed
- Select {ENR} - If using SNS noise source check that {preference} is set to {SNS}
- If using 346 series noise sources use relevant ENR data1
- Connect up set up without DUT being connected and {calibrate}
- Connect up DUT, if extra adapters are required use the {loss comp}ensation feature to remove additional loss
- Display the "view" and "results" in the preferred configuration using the [view/trace] function
[x] = Hard key
{x} = Soft key
1 346 Noise Sources are now delivered complete with a floppy disk containing ENR Data particular to that source. It is possible to copy this data directly into the analyzer and then store, this data can be updated if required after calibration.
