Keysight N1912A – P-Series Dual Channel Power Meter

• Dual channel power meter
• Designed for high-performance measurement of wireless signals such as WiMAX, LTE, and radar
• Peak, average, peak-to-average ratio, rise time, fall time, and pulse width measurements
• 9 kHz to 110 GHz (sensor-dependent)
• Compatible with more than 30 Keysight sensors 

Today’s complex electronic devices have stringent power requirements. Keysight P-Series power meters and sensors deliver the wide bandwidth and high-performance measurements that you need to be confident that your products are meeting their power specifications.

P-Series power meters have a 30 MHz video bandwidth and 100 M-sample/s continuous sampling rate for fast, accurate, and repeatable power measurements. When these meters are used with the P-Series wideband power sensors, they provide up to 40 GHz frequency coverage, wide dynamic range, and extensive measurement capability that has been optimized for aerospace/defense, wireless communication, and wireless networking (IEEE 802.11a/b/g) applications.

P-Series power meters are now LXI (LAN eXtensions for Instrumentation) Class-C compliant instruments which combine the advantages of Ethernet with the simplicity and familiarity of GPIB. This helps test system designers and integrators to create a faster and more efficient system. With the power of ethernet, P-Series power meters reduce the time needed to set up, configure and debug.

Power sensor compatibility 

P series power meters are compatible with over 30 power sensors, including P series wideband sensors, as well as the 8480, N8480 E-Series, and more.

Apart from WiMAX and WLAN presets, the P-Series power meters also offer 100 Msamples/s continuous sampling that ensures glitches are not missed.

• The P-Series power meters’ 30 MHz video bandwidth enables the capture of signals with modulation bandwidth up to 30 MHz
• With their auto trigger hold-off capability, you can capture the complete Downlink or Uplink subframe burst desired within a fixed time span
• Time-gated peak, average and peak-to-average ratio power measurements are automatically displayed to ease analysis of signals

Setting up for radar signal measurements is faster and easier with the P-Series preset. The capture of a radar pulse is further simplified with autoscaling and auto-gating functions. With auto gating set to “perpetually on,” the gates reposition themselves automatically when pulse width changes.

• Up to four independent time gates can be set for individual measurements on one or multiple pulses
• With a frequency range of up to 40/50 GHz and rise/fall times of ≤ 13 ns, you have more than enough to profile high-frequency radar signals in most applications

In designing multi-carrier power amplifiers (MCPA), a wide-bandwidth power meter such as the P-Series helps you ensure that your device stays within its maximum power specification. The P-Series power meter’s 30 MHz video bandwidth allows up to six 3G carriers over a wide dynamic range.

• CCDF and peak-to-average power measurements verify if MCPA is clipping
• 100 MSamples/s continuous sampling ensures easier detection of glitches
• Rise/fall time measurements help in checking the signal’s burst profile and in identifying power transition problems
• High-resolution color display ease viewing and differentiation of the four traces
