The Keysight/Agilent N4431A RF Electronic Calibration (ECal) Module makes the calibration of vector network analyzers fast, easy, and accurate. ECal is a precision, single-connection calibration technique for your vector network analyzer. Performing a full three- or four-port calibration takes less than half the time and a number of connections using ECal versus mechanical cal kits. Furthermore, the accuracy of the calibration is comparable between electronic and mechanical methods. Traditional mechanical calibrations require intensive operator interaction, which is prone to errors. With ECal, the operator simply connects the ECal module to the network analyzer and the software controls the rest. ECal modules are transfer standards capable of transferring the factory calibration accuracy to your network analyzer. The Agilent PNA and ENA series of network analyzers controls the N4431A module directly through a USB interface. Specification : 300kHz to 9GHz Fast full 3- or 4-port calibration with a single connection NIST traceable accurate calibrations Reduced connector wear USB interface for direct control with PNA and ENA series of network analyzers Reliable solid-state switching

Keysight U2020 X-series USB power sensors provides the peak and average power measurement capability of a power meter in a compact and portable form factor. Frequency range of 50 MHz to 40 GHz Wide dynamic range of -30 to 20 dBm (peak/gated), -45 dBm to 20 dBm (average only mode) 30 MHz video bandwidth and single shot real-time capture at 80 Msample/sec per second Internal zeroing & calibration High measurement speed of up to 25,000 readings/second (free run/fast buffer mode) A BenchVue software license (BV0007B) is now included with your instrument. BenchVue makes it simple to connect, control instruments, and automate test sequences.

Main Feataures Include: Option 002 = Phase Modulation <-147 dBc/Hz SSB phase noise at 10 kHz offset 0.1 Hz frequency resolution AM, FM, phase, and pulse modulation in one generator Internal 10 Hz to 99.9 kHz modulation synthesizer

4-slot MMS module 1-20 GHz frequency range, extends to 10 MHz with the 70341A 13 dBm power out Optional step attenuator <-55 dBc harmonics, <-60 dBc spurious User level correction at remote test ports Pulse, FM, log AM modulation, and optional pulse generator The 70340A is a 1 to 20 GHz synthesizer in a 4-slot MMS module. With <-55 dBc harmonics and <-60 dBc spurious, and optional 1 Hz frequency resolution, the 70340A is a smart choice for ATE systems. Because fundamental oscillators are used, no subharmonics are generated. Accurate internal leveling provides ±0.5dB flatness at the RF output. Accurate leveled power can also be extended to distant test ports using a power meter and the built-in level correction. Modulation includes pulse, FM, and log AM. High fidelity pulses are created with <10 ns rise and fall time. An optional built-in pulse generator can be used with variable pulse rates, widths, and delays. Combining pulse modulation with log AM allows realistic simulation of antenna scanning patterns. For frequency coverage from 10 MHz to 20 GHz, the 70340A can be combined with the 70341A frequency extension module.
