Enhance manufacturing test by connecting a large external monitor with the unique VGA output option

As signals become more complex, it becomes more difficult to make fast, accurate power measurements. For years, you’ve depended on Keysight’s EPM Series power meters. Today, the Keysight N1913A and N1914A EPM Series power meters are versatile, user- friendly replacements for the discontinued E4418B/19B EPM Series. Best of all, you get these extras for about the same price. Get consistent results and greater capability—with the new EPM Series power meters.

Using EPM Series with BenchVue Software

The EPM Series is supported by the Keysight BenchVue software’s BV0007B Power Meter/Sensor Control and Analysis app. Keysight BenchVue software for the PC accelerates testing by providing intuitive, multiple instrument measurement visibility and data capture with no programming necessary. You can derive answers faster than ever by easily viewing, capturing and exporting measurement data and screen shots. BenchVue software license (BV0007B) is now included with your instrument

N1913A/14A EPM Series Power Meters Performance Characteristics

Specifications describe the instrument’s warranted performance and apply after a 30 minute warm-up. These specifications are valid over its operating/environmental range unless otherwise stated and after performing a zero and calibration procedure.

Supplemental characteristics (shown in italics) are intended to provide additional information, useful in applying the instrument by giving typical (expected), but not warranted performance parameters. These characteristics are shown in italics or labeled as “typical,” “nominal” or “approximate

E-Series Power Sensor Specifications

The E-Series of power sensors have their calibration factors stored in EEPROM and operate over a wide dynamic range. They are designed for use with the EPM Series of power meters and two classes of sensors are available:

  • CW power sensors (E4412A and E4413A)
  • Average power sensors (E9300 sensors)
