The Agilent N1913A and N1914A are EPM Series average power meters offered as versatile, user-friendly replacements for the E4418B/E4419B EPM Series. The N1913A is a single-channel average power meter and the N1914A is a dual-channel average power meter. Both deliver consistent results and greater capability while remaining code-compatible with the legacy E4418B/E4419B EPM Series instruments, allowing established measurement routines to carry forward.
Across the compatible sensor set, the EPM Series addresses CW, modulated CW, pulse/averaged, and AM/FM profiled signals, along with wireless-standard measurements spanning mobile phone, WLAN, WPAN, and WMAN classes. Typical application examples include metrology lab work, radar and navigation, and mobile radio formats such as GSM, EDGE, GPRS, CDMA2000, cdmaONE, IDEN, 3G, HSPA, and LTE, as well as 802.11a/b/g/n, Bluetooth, RFID, ZigBee, WiMAX, and WiBro — with average-only support indicated for several modulated and wireless formats depending on the attached sensor.
ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, which lets us match the right instrument and sensor configuration to an application directly from equipment we keep on hand. Every used unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer.
Agilent Technologies was established in 1999 as a spin-off of Hewlett-Packard's test and measurement business. In 2014, that electronic measurement business was transferred to Keysight Technologies, which continues the product line today.
The EPM Series spans two average power meters that share frequency coverage, power range, accuracy specifications, and sensor compatibility but differ in channel count. The N1913A is the single-channel model and the N1914A is the dual-channel model, both serving as code-compatible replacements for the E4418B/E4419B EPM Series.
Each model accepts the same families of compatible power sensors — 8480 Series, E-Series E4410 and E9300, N8480 Series, and U2000 Series USB sensors — and shares the color LCD, the GPIB/USB/LAN interface set, and the internal 1 mW, 50 MHz power reference.
Each model below links to its own dedicated product page with condition-matched pricing for the pre-owned configuration you select. Choose the model that matches your channel-count and code-compatibility requirements, then select the listing for your preferred condition.
The N1913A single-channel meter offers optional code compatibility with the 436A and 437B; the N1914A dual-channel meter offers optional code compatibility with the 438A. On the N1914A, measurement speed is reduced when both channels operate — for example, with both channels in Fast mode the typical maximum is 200 readings per second — and the rear-panel recorder outputs are dedicated to channel A and channel B.
The principal difference across the family is channel count: the N1913A measures a single channel while the N1914A measures two channels, expandable to a total of four channels on either model through optional USB sensor ports. Measurement-speed behavior also differs, since the dual-channel N1914A's typical maximum speed depends on how many channels are active.
Optional 43X code compatibility differs by model as well — 436A/437B on the N1913A and 438A on the N1914A — along with standalone code-compatibility upgrade options. See the comparison table for the model-by-model breakdown of channels, code compatibility, and net weight.
| Model | Channels | Frequency Range | Power Range |
|---|---|---|---|
| N1914A | 2 (up to 4 with optional USB) | 9 kHz to 110 GHz | –70 dBm to +44 dBm (100 pW to 25 W) |
| N1913A | 1 | 9 kHz to 110 GHz | –70 dBm to +44 dBm (100 pW to 25 W) |
Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.
Replaces: per the manufacturer, this model replaces E4418B, E4419B.

Important: Fast measurement-speed mode (up to 400 readings/second) is available with Agilent E-Series power sensors only.
Important: A compatible power sensor (Agilent 8480 Series, E9300/E4410 E-Series, N8480 Series, or U2000 Series) is required to make power measurements and is NOT included in the standard-shipped accessories; the appropriate sensor must be ordered separately (the meter ships with power cord, sensor cable, USB cable, CD-ROMs and calibration certificate only).
Important: 436A/437B/438A code (43X) compatibility is available only with option N191xA-200: the N1913A is backward compatible with the 436A and 437B, while the N1914A is compatible with the 438A.
Important: The N1913A/14A power meters are compatible with all 8480 Series power sensors, including discontinued models.
Important: Battery operation (single-button battery confirmation and operating time) applies only to models ordered with the battery option (N1913/4A-B02).
