# Keysight N1914A Dual-Channel EPM Series Power Meter # Keysight N1914A Dual-Channel EPM Series Power Meter ## Key Features At A Glance - Single-channel (N1913A) or dual-channel (N1914A); expandable to four channels via optional USB sensor ports - Frequency coverage 9 kHz to 110 GHz and power range –70 to +44 dBm (100 pW to 25 W), sensor dependent - Measurement speed up to 400 readings/sec with Keysight E-Series power sensors - Meter absolute accuracy ±0.02 dB / ±0.5% (add sensor linearity for overall system accuracy) - Industry's first high-resolution color LCD readout in an average power meter - GPIB, USB 2.0, and 10/100BaseT LAN/LXI-C interfaces (IEEE 488.2, SCPI) for automated test systems - Optional 43x code compatibility to replace 436A, 437B, and 438A power meters; BenchVue BV0007B license included The Keysight N1913A and N1914A are EPM Series power meters built for RF average power measurements. The N1913A is a single-channel average power meter and the N1914A is a dual-channel average power meter. Both are positioned as versatile, user-friendly replacements for the discontinued E4418B/19B EPM Series, and the power range available on any given measurement depends on the connected power sensor. These meters support the full set of measurement scenarios laid out in the compatible-sensor table: continuous-wave (CW) signals for metrology-lab and mobile-radio work, pulsed and averaged signals for radar and navigation, and modulated signals across wireless standards including GSM, EDGE, GPRS, cdma2000, cdmaONE, iDEN, 3G, HSPA and LTE mobile-phone formats, 802.11a/b/g/n WLAN, Bluetooth, RFID, ZigBee, WiMAX and WiBro. The specific signal types each sensor class supports vary, with several wireless-standard measurements available in average-only mode. ValueTronics has specialized in new and used test-and-measurement equipment since 1992, operating from a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold our own inventory. ## Brand Heritage Keysight Technologies traces its instrument heritage to Hewlett-Packard, whose test-and-measurement business was spun out as Agilent Technologies in 1999 and then established as Keysight Technologies in 2014. Much of the EPM Series and its compatible sensor line carries this lineage forward. ## Compare Other Models in This Series The EPM Series spans two power-meter models that share the same measurement architecture, accuracy, color display, and remote-interface set, differing primarily in channel count. The N1913A is a single-channel average power meter and the N1914A is a dual-channel average power meter. Both models accept the full range of compatible Keysight power sensors — 8480 Series, E4410 and E9300 E-Series, N8480 Series, U2000 and U8480A USB sensors, and U2040/50/60 X-Series — with the usable frequency and power range set by the connected sensor. Each new model below is its own dedicated product page with condition-matched pricing. Select the model that fits your channel-count and code-compatibility requirements, and review that page's specifications and availability. The N1913A is backward compatible with the 436A and 437B power meters via the optional 43x code-compatibility option (N1913A-200, or N6901A-1FP as a post-purchase upgrade), making it a direct programmatic replacement in existing single-channel test systems. The core difference between the models is channels: the N1913A measures a single channel while the N1914A measures two channels simultaneously and can display any two of A, B, A/B, B/A, A-B, B-A and relative. With the optional USB ports, both can expand to four channels (C and D). Measurement speed and code compatibility also differ. In fast mode with E-Series sensors the N1913A reaches 400 readings/second, while the N1914A reaches a typical 200 readings/second with both channels in fast mode. For legacy code compatibility, the N1913A maps to the 436A and 437B and the N1914A maps to the 438A. See the comparison table for the per-model details. Model Channels Code Compatibility Max Measurement Speed **N1914A** 2 438A 200 readings/sec (both channels FAST) N1913A 1 436A / 437B 400 readings/sec N1913A 1 436A / 437B 400 readings/sec Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below. ## Accessories Supplied - Power cord - Power sensor cable, 1.5 m (5 ft) (two per N1914A) - USB cable Type A to Mini-B, 6 ft - BenchVue BV0007B Power Meter/Sensor Control and Analysis app license (included) > **Replaces:** per the manufacturer, this model replaces [E4418B](/products/e4418b-agilent-rf-power-meter-used), [E4419B](/products/e4419b-agilent-rf-power-meter-used). ## Product Core & Specifications Specification Value Performance Characteristics Compatible power sensors Keysight 8480 Series; Keysight E9300 E-Series; Keysight E4410 E-Series; Keysight N8480 Series; Keysight E8486A, V8486A, W8486A; Keysight U2000 Series; Keysight U8480A Series; Keysight U2040/50/60 X-Series (except U2049XA & U2042/44/60 X-Series in Average mode only) Frequency range 9 kHz to 110 GHz, sensor dependent Power range –70 to +44 dBm (100 pW to 25 W), sensor dependent Single sensor dynamic range 90 dB maximum (Keysight E-Series power sensors); 50 dB maximum (Keysight 8480 Series power sensors); 55 dB maximum (Keysight N8480 Series power sensors); 80 dB maximum (Keysight U2000 Series USB power sensors); 55 dB maximum (Keysight U8480A Series USB power sensors); 96 dB maximum (Keysight U2040/50/60 X-Series, except U2049XA & U2042/44/60 X-Series in Average mode only) Display units Absolute: Watts or dBm.
