Step 1. Select the model that provides the desired frequency range.
Model Description Frequency Test port connectors
N9925A 9 GHz FieldFox microwave VNA 30 kHz to 9 GHz Type-N (f)
N9926A 14 GHz FieldFox microwave VNA 30 kHz to 14 GHz Type-N (f)
N9927A 18 GHz FieldFox microwave VNA 30 kHz to 18 GHz Type-N (f)
N9928A 26.5 GHz FieldFox microwave VNA 30 kHz to 26.5 GHz 3.5 mm (m)
A standard N992xA FieldFox microwave VNA includes transmission/reflection measurement capability. Additional functionality such as
full 2-port S-parameters can be added using the options listed below.
Step 2. Select optional measurement capabilities.
Any of these options can easily be added as a software upgrade in the future.
