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 fail-
ures 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 com-
ponents 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 sec-
ond. There’s also a x2 mode with the EPM
series power meters and 8480 series sensor
combination—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 meas-
urement 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 rack-
mount systems. The following options are
available

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.
