Instantly and Precisely Characterize Transmitter Power
The N9937A FieldFox 18 GHz microwave spectrum analyzer provides industry-leading amplitude accuracy of ±0.5 dB at power-up, with no warm-up required. It can can detect more signals in the band of interest with phase noise of -111 dBc/Hz at 10 kHz offset, and measure low-level signals in the presence of high-power transmitters with spur-free dynamic range of 105 dB.
Get Precise Measurements that Agree with Benchtop Results
The spectrum analyzer's base function is spectrum analysis, and can be configured to include; full-band tracking generator and preamplifier, interference analyzer, VSWR and reflection measurements, built-in power meter, USB power sensor support, GPS receiver and DC bias voltage source.
Noise Figure Analyzer Mode (Opt. 356)
Expanding measurement capabilities include noise figure analyzer mode — a key performance parameter in many RF systems. FieldFox can characterize the noise figure of devices including low noise amplifiers (LNAs), frequency converters and receivers using the industry proven Y-factor technique. By combining noise figure measurements with full 2-port vector network analysis, spectrum analysis and power sensor integration, FieldFox can now provide complete characterization of amplifiers and converters in the field or repair depots.
Dust-free design with no fans, no vents extends instrument reliability in harsh environments, water-resistant, MIL-PRF-28800F Class 2 compliant, and MIL-STD-810G, Method 511.5 Procedure I requirements for operation in explosive environments (type tested). Well-suited for: satellite communications, microwave backhaul, Military communications, radar systems, and active and passive device testing.
