Calibration for NA, CAT, and VVM ModesFUTURE

— A THRU standard is used during some calibration steps to connect PORT 1

Calibration Reference Plane is the point (or points) at which the DUT and cal

standards are connected during a calibration. This can be at the FieldFox test

port connectors, or at the end of jumper cables or adapters.

CalReady

Every FieldFox contains a factory calibration that was performed at the port 1

and port 2 connectors, with –15 dBm input power, over the entire frequency

range of the FieldFox using a number of data points that allows reasonable

interpolation over the FieldFox frequency range.

This calibration, known as CalReady, allows you to immediately make

measurements of a DUT that is connected directly at the test ports (PORT 1

and/or PORT 2). CalReady corrects measurements when the FieldFox is turned

ON and when a measurement is created with no other correction in place.

When measuring a DUT using a jumper cable or adapter - NOT a direct

connection to a test port connector – then a Mechanical Cal is recommended.

CalReady can also be used to check the integrity of the jumper cable that is

attached to the test ports.

You can change the properties of the CalReady calibration. Learn more in

Press Esc at any time to end the calibration process.

When performing a calibration that contains a large number of points

(5000 to 10,001 points) be aware that the calibration progress bar may not

move for 2 or 3 minutes during the calibration process.

In CAT, NA, or VVM Mode, press Cal 5.

scope of this discussion. Although an OPEN standard is a precision

component, simply leaving nothing connected at the end of a cable

can be a reasonable substitute for an OPEN.

— A LOAD standard absorbs almost ALL of the incident signal and very

little signal is reflected back to the source.

to PORT 2 in place of the DUT. A Flush THRU connection can be made

when cables that connect with the DUT can mate with each other. Learn
