Agilent Technologies E8285A Data Functions Keys, Guidelines for Using Measurement Data Functions

Chapter 1, Description of Keys

DATA FUNCTIONS Keys

DATA FUNCTIONS Keys

The DATA FUNCTIONS keys can be divided into two groups; those which affect measurements (Ref set, Meter, Average, High limit and Low limit), and those which affect numeric entry fields (Increment÷10, Increment set, Increment×10, up-arrow, down-arrow). For measurements, the data functions enable the programmer to change the way measurements are calculated and displayed, and provide measurement limit detection. For numeric entry fields, the data functions enable the programmer to set, scale, and change the field’s increment value.

Refer to the “Number Measurement Syntax” in the GPIB Command Syntax chapter of the E8285A Condensed Programming Reference Guide for full command syntax.

Guidelines for Using Measurement Data Functions

•Data functions are turned ON and OFF for individual measurements. The GPIB Data Function commands must immediately follow the GPIB command for the individual measurement. For example, to turn the Average data function ON for the AF Analyzer distortion measurement, the following command string would be sent to the Test Set:

OUTPUT 714;"MEAS:AFR:DISTN:AVER:STAT ON"

•Attribute Units (AUNits) are used with the data functions to specify the units-of- measure for numeric data which is read or set through GPIB.

Refer to “To Specify Units-of-Measure for GPIB Data Transfer” in the Operating Overview chapter of the E8285A User’s Guide .

•Data function settings, such as number of averages or reference value, are retained if the function is turned off. The setting values are initialized or changed under the following conditions:

•The Test Set is turned off.

•The Test Set is preset.

•A saved register is recalled.
