Introduction
Introduction
One of the first things yo u will want to do with your power meter is to
switch it on and become acquainted with its front panel. The sections in
this chapter prepare the power meter for use and help you get familiar
with some of the front panel operations.
The front panel consists of both hardkeys and softkeys which allow you to
select various funct ions an d opera tions. When so me hardkeys are se lect ed
the corresponding softkey labels are displayed on the power mete r display.
If you are using the power meter remotely refer to the Agilent
Technologies E4418B/4419B Programming Guide for remote operating
details.

Getting Started
Turning On the Power Meter
Turning On the Power Meter
The following steps show you how to turn on the power meter and verify
that it is operating correctly.
1. Connect the power cord and turn on the power meter.
The front panel display and the green power LED light up when
the power meter is switched on. The power meter performs it’s
power on self test. If the self test is not successful the error
annunciator turns on. If this occurs contact your Agilent
T e chnologies Sales and Service office for instructions on returning
the power meter to Agilent Technologies for service.
Caution This instrument is designed for use in Installation Category II and
Pollution Degree 2 per IEC 1010 and 664 respectively.
Caution This instrument has an autoranging line voltage input, be sure
the supply voltage is within the range of 85 to 264 Vac.
Note If the power meter has been stored a t extremely l ow temperature s
outwith the operating range of the power meter, the display may
take a few minutes to operat e.
2. Set the display contrast if required.
The display contrast is adjusted by pressing and . If
these softkeys are not displayed press repeatedly until they
Prev
appear.
3. Connect a power sensor.
Connect one end of the sensor cable to the power meter’s channel
input and the other end to the power sensor.
4. Making a measurement.
A minimum warm up time of 30 minutes is recommended before
accurate measurements can be made.
Prior to making your first measurement you must zero and
calibrate the sensor and meter combination. Refer to Chapter 2 for
further information if you are not familiar with zeroing,
calibrating or making measurements with a power meter.

1. The status reporting line displays five fields, three associated with
either GP-IB, RS232 or RS422 status and two associated with
error and warning conditions. The first field displays either “RMT”
(remote, GP-IB, RS232 or RS422 operation) or “LCL” (local, front
panel operation).
For GP-IB operation, the second field displays “TLK” if the power
meter is addressed to talk or “LSN” if it is addressed to listen. The
third field indicates an “SRQ” (service request).
For RS232 and RS422 operation, the second field displays “RX”
when data is being recei ved. The third field displays “TX” when the
power meter is transmitting data.
