Current

When set to Current, this field displays the DC current measured at the DC CURRENT MEAS port on the back of the Test Set. Any offset can be removed by selecting Zero in the DC Current field.

This field is a one-of-many field used to select the type of measurement to be made by the Audio Frequency Analyzer on the audio signal being measured. See “Measure” in the GPIB Command Syntax chapter of the E8285A Condensed Programming Reference Guide for programming command syntax.

Selecting this field displays the following measurement choices:

SINAD

Distn (Distortion)

SNR (Signal to Noise Ratio)

AF Freq

DC Level

Current (DC only)

Operating Considerations

This is a priority control field. Accessing the RX TEST or TX TEST screen overrides any changes made to this field in other screens.

For more information about SNR operation, see the SNR field description, on page 398.
