Before Connecting a Radio
Before Connecting a Radio
NOTE: The RF IN/OUT port should be u sed for all transmitter tests when t he radio is connected
directly to the Test Set. (All MSUT (Mobile Station Under Test) transmitter power
measurements are made through this port). Off-the-air measurements can be made using
the highly-sensitive ANT IN port .
CAUTION: Overpower Damage — Refer to the T e st Set’s front panel for maximum input po wer level .
Exceeding this level can cause permanent instrument damage.
Overpower Damage — Blocking the fans’s rotation or operating the Test Set in
an environment that causes excessive heat may cause damage.
Important: If excessive temperatures are sensed on the power supply regulator
assembly, the Test Set’s power supply will shut off. After temperature has
lowered to within normal operating range, use the POWER switch to cycle power
on. Remove RF power from the RF IN/OUT connector whenever the Test Set is
off.

Obtaining Measurement Results
Setting Up a Call
To obtain CDMA measurements, the Test Set must have the MSUT (Mobile
Station Under Test) on a call (the Connected annunciator on the CDMA CALL
CONTROL screen is lit when the MSUT is on a call).
The procedure for sett ing up a c all i s provi ded in “Se tting Up a Cal l”, found in the
Agilent Technologies E8285A Application Guide. In the Agilent E8285A
Application Guide, there are also procedures for performing CDMA tests.
Triggering and Displaying Measurements
When operated over the front panel (local control), Test Set measurement results
are obtained by selecting a screen that displays the desired measurement, arming
the measurement if necessary, and observing the displayed value.
When operated remotely, measurement results are obtained via GPIB by
triggering a measurement if necessary and querying the desired measurement
field.
NOTE: In CDMA mode, transmitter (TX) measurements and receiver (RX) measurements can run
concurrently. For example, an Average Power or Channel Power measurement can be queried
while the RX TEST screen is selected and an FER measurement is running.
For a detailed description of triggering measurements, see "Measurement
Triggering Process" on page 73
.

Preparing the Test Set for GPIB Control
1. If other GPIB devices are in the system, attach an GPIB cable from the Test Set’s rear-
panel GPIB connector to any one of the other devices in the test system.
2. Access the I/O CONFIGURE screen and perform the following steps:
a. Set the Test Set’s GPIB address using the GPIB Adrs field (see "Addressing"
on page 34).
b. Set the Test Set’s GPIB Controller capability using the Mode field.
• Talk&Listen configures the Test Set t o be control led throu gh GPIB with an
external controller. The Test Set has Active Controller capability (take control/
pass control) in this mode.
• Control configures the Test Set to be the system controller. Use this setting
if the Test Set will be the only controller on the GPIB. Selecting Control
automatically makes the Test Set the active controller.

Obtaining Measurement Results
NOTE: Only one active controller is allowed on the GPIB at one time!
3. If an GPIB printer is or will be connected to the Test Set’s rear-panel GPIB connector,
perform the following steps:
a. Access the PRINTER CONFIGURE screen.
b. Select one of the supported GPIB printer models using the Model field.
c. Set the Printer Port field to GPIB.
d. Set the printer address using the Printer Address field.

General Programming Procedure
1. For each measurement you want to perform programmatically, make the measurement
manually using the front-panel controls of th e Test Set. Yo u will find procedures for
making measurements in the Agilent E8285A Application Guide. Record, in sequential
order, the screens selected and the settings made within each screen.
2. Record the measurement result(s).
3. Develop the program using the measurement procedure generated in step 2. For CDMA
measurements, the Agilent E8285A Application Guide provides step-by-step GPIB
command examples.
4. Make sure the desired measurement is selected and in the ON state. This is the PRESET
state for most measurements. However, if a previous program has set the state to OFF,
no measurement result will be available. Attempting to read from a measurement field
that is not in the ON state will cause GPIB Error:-420 Query
UNTERMINATED.
5. Trigger the desired measurement if the RETRigger MODE is SINGle. You will find
that the Test Set automatically enters REPetitive trigger MODE for CDMA measurements when an GPIB command is sent to it.
6. Send the appropriate MEASure query command to initiate a reading. This will place the
measured value into the Test Set’s Output Queue.
7. Use the ENTER statement to transfer the measured value to a variable within the con-
text of the program.
