Controlling the Test Set and Making Measurements

Commands

Making Measurements

The following examples assume that you are using a parallel port

connection with an Agilent 8753D/E, with the test set parallel address

set to 0. Refer to “Setting the Test Set Address Switch” on page 2-3, for

information on setting the test set address.

Measuring Transmission

Refer to Figure 5-3 on page 5-11 for the following discussion. With the

Agilent 8753D/E set to measure forward transmission (S

), the

analyzer RF source is being output through the analyzer Port 1, and

Port 2 is set to receive the RF signal.

By using the following commands, you will connect Port 3 of the test set

to the Reflection port, and you will connect Port 7 of the test set to the

Transmission port. You will thus be measuring forward transmission

through the device under test when measuring S

. This will provide

you with gain or insertion loss information.

If controlling the Agilent 87050A Option H15 directly, use the following

GPIB (HP-IB) commands:

OUTPUT 716;"PARALGPIO;"

OUTPUT 716;”PARAOUT2;”

OUTPUT 716;”PARALGPIO;”

OUTPUT 716;”PARAOUT6;”

OUTPUT 712;"refl_03"

ENTER 712;”tran_07”
