FieldFox Microwave Spectrum Analyzers
FieldFox microwave spectrum analyzer models
Step 1. Select the model that provides the desired frequency range.
Model Description Frequency range
1
Test port connectors
N9935A 9 GHz FieldFox microwave spectrum analyzer 100 kHz to 9 GHz Type-N (f)
N9936A 14 GHz FieldFox microwave spectrum analyzer 100 kHz to 14 GHz Type-N (f)
N9937A 18 GHz FieldFox microwave spectrum analyzer 100 kHz to 18 GHz Type-N (f)
N9938A 26.5 GHz FieldFox microwave spectrum analyzer 100 kHz to 26.5 GHz Type-N (f)
2
N9960A 32 GHz FieldFox microwave spectrum analyzer 9 kHz to 32 GHz NMD 2.4 mm (m)
N9961A 44 GHz FieldFox microwave spectrum analyzer 9 kHz to 44 GHz NMD 2.4 mm (m)
N9962A 50 GHz FieldFox microwave spectrum analyzer 9 kHz to 50 GHz NMD 2.4 mm (m)
1. The spectrum analyzer can be tuned to 5 kHz.
2. Order Option 100 for 3.5 mm (m) test port connectors. With N9938A-100, the spectrum analyzer is built with 3.5 mm test port connectors instead of the
standard Type-N (f). Option 100 is a prerequisite for Option 320 for N9938A.
3. Requires CPU2 fast processor. See page 6, FAQ #13
4. List of compatible power sensors available from www.keysight.com/find/fieldfoxsupport
Step 2. Select optional measurement capabilities.
Any of these options can easily be added as a software upgrade in the future.
