I'm using a program to read/control an E5100A NA and a line simulator (simulates long lengths of wire... thousands of feet). The program is being tried on a newer line simulator that takes much longer to respond to commands. The program was reading incorrectly at this point because it was designed for the faster response time of the previous line sim.
The quick-fix was determined to be slowing down the sweep time of the NA. This got us around the timing problem, but now the attenuation measurements are higher than they should be.
I know that changing the IF BW, number of points, and start/stop freq's all affect the calibration, but does the sweep time affect it as well?
Thank you,
Charles

In general, always use step-sweep and slow the sweep until no more changes are seen. this applies to both the measurement and the calibration.
