Example 5:

Computer controlled measurements

with user flatness corrections

This section focuses on computer controlled meas-

urement systems. The following program interrogates

the source and a 437B power meter for frequency

and power information respectively. The source

(83620B) is programmed to sweep from 2 to 20 GHz,

with user flatness corrections every 100 MHz and

+5 dBm leveled output power. It is assumed that

the path losses do not exceed 5 dBm and that the

437B power meter already has its power sensor’s

calibration factors stored in sensor data table 0. If

another power meter is utilized, the power sensor’s

calibration factors will have to be stored in a look-up

table. Modify the program to suit your particular

measurement requirements. Up to 801 points may

be entered in the user flatness correction table

with this program.

TMSL commands (see figure 11a) are used to set

up the source parameters and enter correction

frequencies and data into the user flatness correction

table. The TMSL commands are written in capitalized

and lower case letters. The capitalized portion of

each command illustrates the short form. Commands

may be written in either the short or the long form,

or any combination of the two. Refer to the 8360

User’s Guide for more details on TMSL commands.
