SCPI compatible - EPM power meters conform to the
Standard Commands for Programmable Instruments
(SCPI).
RS232/422 interface - both RS232 and RS422 serial
interfaces can be used to remotely control the EPM
series power meters.
Limit testing - EPM series power meters can be
configured to verify the power being measured
against an upper and / or lower limit. Limit failures
are indicated on the power meter’s display and over
the GPIB.
Zero/Cal lockout - can be enabled to prevent the
EPM series power meter from making measure-
ments until the connected sensor is zeroed and
calibrated.
Channel offset - EPM series power meters can
be configured to compensate for signal loss or
gain in your test setup.
Designed for Manufacturing
Fast speed means increased productivity
Fast measurement speed is essential in the high
volume manufacturing of RF and microwave compo-
nents and systems. Faster test time improves your
productivity—letting you test more devices in less
time. E-series sensors along with the E4418B
power meter provide a FAST measurement mode
that lets you make up to 200 readings per second.
There’s also a x2 mode with the EPM series
power meters and 8480 series sensor combina-
tion—doubling your speed compared to the
437B and 8480 series combination.
No more slow range switch delays!
A common problem with most power meters
is the time delay that occurs when the power
being measured crosses a range switch point.
Range switching delays are either significantly
reduced or eliminated when an EPM series
power meter is used with an E-series sensor.
This power measurement combination has
only one fast range switch point across the
entire dynamic range of the sensor.
Height and width compatibility allows
easy replacement in rackmount systems
The EPM series power meters are the same
height and width as the 437B and 438A—
making them easy to substitute in rackmount
systems. The following options are available
2
:
Option 002 - rear panel sensor input(s) with
the Power Reference Calibrator
on the front panel.
Option 003 - rear panel sensor input(s) with
the Power Reference Calibrator
on the rear panel.
Option 908 - rackmount kit for one instrument.
Option 909 - rackmount kit for two instruments.

These options are available for an extra cost.
Rigorous environmental testing and high-reliability qualifies the
EPM power meters for your most demanding measurement applica-
tions.
