a. The temperature range over which the calibration standards maintain performance to their specifications.
b. The allowable network analyzer ambient temperature drift during measurement calibration and during mea-
surements when the network analyzer error correction is turned on. Also, the range over which the network
analyzer maintains its specified performance while correction is turned on.
Temperature—What to Watch Out For
Changes in temperature can affect electrical characteristics. Therefore, the
operating temperature is a critical factor in performance. During a
measurement calibration, the temperature of the calibration devices must be
stable and within the range shown in
IMPORTANT! Avoid unnecessary handling of the devices during calibration
because your fingers act as a heat source and may increase the
temperature of the device.
