VNA Receiver Mode

[Squirtle]

Hello, i want to measure two signals with 2-port VNA. However for this case i need to use both ports of the VNA as receiver. I am using field-fox handheld microwave analyzer. Does this product support this feature?

Thankyou for showing the datasheet

All VNA's have 2 Rx and 1 Tx but S/W is user selectable $$ on the Fieldfox and there are many versions of this brand

Yes, but the Rx channels aren't independent and usually activated sequentially. Fieldfox series has many features and options but I don't recognize dual Rx at first sight. Ask Keysight support.

So i can use both of the ports as receiver however i can't use them simultaneously. I need to switch between them. Field Fox has absolute measurement feature.

I was describing general operation principle of VNA. Actual capabilities of FieldFox instrument must be verified according to manufacturer information.

I recall the FieldFox series, when configured as a full 2-port VNA with Option 211 or similar, depending on the model), does use a dual-receiver architecture internally.
