Calibration for NA, CAT, and VVM Modes See Also Learn How to Make 75 ohm Measurements at the FieldFox Supplemental Online Help: http://na.support.keysight.com/fieldfox/help/SupHelp/FieldFox.htm Why and When to Calibrate There are well-defined and understood systematic errors that are measured and calculated during the calibration process. These errors are caused by leakage signals inside the FieldFox, by the frequency response of the FieldFox receivers, and by reflections inside the FieldFox that interact with the DUT.
Page 123: Calready
Calibration for NA, CAT, and VVM Modes 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.
Page 124 Calibration for NA, CAT, and VVM Modes The following appears: Choose Calibration Method screen — Response Cal – Used to quickly calibrate ONE type of measurement using mechanical standards. Measurement accuracy is generally low. Learn more “Simple Response Cals ” on page 132.
Page 125: Quickcal (N991Xa/2Xa/3Xa Only)
Calibration for NA, CAT, and VVM Modes Source Unleveled errors - During calibration, the frequency range of the measurement MAY be extended to provide maximum flexibility. During the calibration, the output power may become unleveled at the added high frequencies. You can ignore the “Source Unleveled” error, or to avoid the error, select either High power or -15 dBm before calibrating.
Page 126 Calibration for NA, CAT, and VVM Modes — The connector choices that are offered depend on the frequency range. For example, if you have selected a frequency range that exceeds 18 GHz, the only connector options you will be presented with in QuickCal are 'other 50 ohm' or 'other 75 ohm'.
Page 127: Mechanical Cal
Calibration for NA, CAT, and VVM Modes — When your DUT has high return loss such as the reject band of a filter. Then measuring the load improves accuracy. Even with the optional Load, phase accuracy begins to degrade when the return loss is greater than about 20dB.
Page 128 Calibration for NA, CAT, and VVM Modes — If a jumper cable or adapter is required to connect the DUT to the FieldFox, then connect those components to the FieldFox connectors. The effects of those components will be measured and removed during the calibration, and only the effects of the DUT will be displayed in the measurement results.

Page 130: Ecal
Calibration for NA, CAT, and VVM Modes ECal ECals each have a recommended input power level. Depending on the measurement setup, the FieldFox may default to an input power level that exceeds your ECal’s recommended input power level. Refer to the reference guide for your ECal module to determine the correct input power levels.
Page 131 Calibration for NA, CAT, and VVM Modes Select an ECal module that has connectors of the same type and gender as the DUT. If such an ECal module is not available, a module with connectors different from the DUT can be used by selecting a User Characterization.

Page 585: Calibration Wizard
Noise Figure Mode (Option 356 – CPU2 Only) Calibration Wizard Calibration Wizard The Noise Figure mode has two types of calibration wizard softkeys: Receiver Cal and User Cal. A receiver calibration is required for a user calibration. On the Fieldfox, after you have completed a user calibration, the User Cal (User Cal) annotation overwrites the displayed Receiver Cal (Rcvr Cal) annotation.
Page 586 Noise Figure Mode (Option 356 – CPU2 Only) Calibration Wizard receiver calibration has virtually no influence on the noise figure measurement, either with or without a user calibration. The receiver calibration only effects the gain measurement, and only when there is no user calibration. As already stated, the receiver calibration measures the measurement bandwidth of the receiver.
Page 587 Noise Figure Mode (Option 356 – CPU2 Only) Calibration Wizard — When the DUT output noise power is relatively low (i.e., the gain plus noise figure of the DUT is less than 15 dB), measurement accuracy may also be improved by using a low loss isolator on the preamplifier input. Due to the output reflection coefficient of the DUT, reverse noise waves from the preamplifier, when present, will contribute a different amount of noise power during the measurement of the DUT than during the user calibration.
