Carry Precision With You To Ka Band & Beyond
The N9961A FieldFox is a rugged, dependable handheld analyzer designed to deliver precise, lab-grade measurements. Offering more built-in capabilities than similar analyzers, you can replace the hassle of carrying three or four instruments with a single FieldFox.
Instantly and Precisely Characterize Transmitter Power
The N9961A FieldFox 44 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.
