How to Perform a Calibration
In CAT, NA, or VVM Mode, press Cal 5.
The following appears:
Choose Calibration Method screen
Response Cal – Used to quickly calibrate ONE measurement using mechanical
standards. Measurement accuracy is generally low. Learn more on page 68.
Quick Cal – Using built-in cal standards and CalReady, quickly and accurately
calibrate measurements when using a jumper cable or adapter to connect the
DUT to the FieldFox test ports. Learn more on page 64.
Mechanical Cal – Using mechanical cal standards from a cal kit, perform an
accurate calibration at one or both test ports, adapters, or jumper cables. Full 2-
port mechanical calibration is the most accurate calibration available with
FieldFox. Learn more on page 66.
Cal ON OFF – Turns ON and OFF the effects of the user calibration that you
performed. The OFF state reverts to CalReady which can never be turned OFF.
View Cal – Shows the properties of the current calibration. Learn more on page
69.
More – Learn about Cal Ready Properties on page 72.
NOTE Press Esc at any time to end the calibration process.
QuickCal
QuickCal is ideal for a quick and simple calibration of the measurement when
using a jumper cable or adapter to connect the DUT to the FieldFox test ports.
QuickCal corrects for phase shift, time delay, and loss of adapters or jumper
cables.
QuickCal does not require a specific Cal Kit and is a very simple calibration. If
the highest accuracy is required, a mechanical calibration with a high quality
calibration kit is recommended.
QuickCal is designed and most accurate when calibrating for DUTs fitted with
Type-N and 7/16 connectors.
If the DUT has different connectors, such as 3.5 mm (male) or SMA male
connectors, QuickCal can still be used by selecting 'Other' connector. However,
the accuracy of QuickCal with ‘Other’ connectors is not specified.
