RE: VI to measure power with Agilent E4404B

Hi All,

I have developed a VI based on the Agilent ESA PSA series instrument driver library to measure power with the E4404B.

The process is straight forward and intends to replicate the following manual procedure:

1. Preset
2. Set Center frequency
3. Measure > Channel Power
4. Meas Setup > Avg Number > 100
5. Set Integration BW(IBW)
6. verifying Span = 1.5 * IBW
7. Optimize ref level
8. Read Channel power

The FW version on the Spectrum Analyzer is A.14.06 which is the latest and I am using the NI GPIB-USB HS to control the instrument.

I have two issues with this VI:

1. Although using the instrument driver's "close", The Spectrum analyzer remains in the remote mode, how do I get it to go to local at the end of the VI?
2. Another issue is that after taking the measurement (completing the averages)the instrument's screen freezes, where as I want it to go back to the normal mode so that I can keep monitoring my input signal i.e. same behavior as manual power measurement

Any ideas how I can correct these two?

Thanks
