located under the 1Menu) key, is the standard sweep mode of the analyzer, in which the sweep is triggered automatically and continuously and the trace is updated with each sweep.

brings up the conversion menu which converts the measured data to impedance (Z) or admittance (Y). When a conversion parameter has been defined, it is shown in brackets under the

softkey label.

If no conversion has been defined, the softkey

turns error correction on or off. The analyzer uses the most recent calibration data for the displayed parameter. If the stimulus state has been changed since calibration, the original state is recalled, and the message “SOURCE PARAMETERS CHANGED” is displayed.

switches the counter to count the analog bus.

switches the counter to count the Al4 fractional-N VCO frequency after it has been divided down to 100 kHz for phase-locking the VCO.

switches the counter to count the Al4 fractional-N VCO frequency at the node shown on the overall block diagram.

switches the internal counter off and removes the counter display from the LCD.

is used to set the frequency for power sweep and CW time sweep modes If the instrument is not in either of these two modes, it is automatically switched into CW time mode.

turns on a sweep mode similar to an oscilloscope. The analyzer is set to a single frequency, and the data is displayed versus

this math function ratios channels 1 and 2, and puts the results in the channel 2 data array. Both channels must be on and have the same number of points Refer to Chapter 2, “Making Measurements” for information on how to use this function to make gain compression measurements.

displays both the current data and memory traces.

specifies whether or not to store the error-corrected data on disk with the instrument state.
