a. The temperature range over which the calibration standards maintain conformance to their
specifications.
b. The allowable network analyzer ambient temperature drift during measurement calibration
and during measurements 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
Table 2-1.
IMPORTANT Avoid unnecessary handling of the devices during calibration because your
fingers are a heat source.
