Installation, Verification, and Maintenance

As high-frequency technologies develop and extend beyond the lab, the need for portable, high-performance test gear increases. FieldFox handheld analyzers are able to withstand the toughest RF and microwave measurement environments regardless of test site location. Install, verify, and maintain systems in the field using one unit that supports over 25 measurement capabilities.

FieldFox’s software options provide the same precision and accuracy as the Keysight equipment on your lab bench. You can customize your configuration at initial purchase or upgrade later with license keys that you can quickly and easily install in the field. There is no need to send the unit back to upgrade it.

Find us at www.keysight.com

FieldFox offers two series in the product family that differ in frequency range and bandwidth. The A-Series models have frequency coverage from 100 kHz to 50 GHz with 10 MHz of bandwidth, while the B-Series models have frequency coverage from 9 kHz to 54 GHz and up to 120 MHz of bandwidth. To see a side-by-side comparison of the A-Series versus B-Series specifications, please see the flyer FieldFox Microwave Analyzers:

B-Series vs. A-Series Specifications.

FieldFox has three base configurations to choose from — vector network analyzer (VNA), cable and antenna tester (CAT), and signal analyzer (SA). You can also configure your unit as a combination analyzer that supports all of the base functions and more. Figure 1 shows a visual representation of the FieldFox family of instruments.

320.

2. Option 320 is not applicable to models N991xA/B,N995xA/B, or N992xA. These models include reflection measurements of return loss and VSWR. There is no need for an Option 320 on these analyzers.

3. On the N991xA/B or N995xA/B model analyzers, order Options 233 and 210 to obtain a tracking generator with the spectrum analyzer. There is no Option 220 on these analyzers. Option 233 provides the spectrum analyzer capability and Option 210 offers the “tracking” capability.
