Environmental Requirements
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 specified in Table
2-1 .
IMPORTANT Avoid unnecessary handling of the devices during calibration because your
fingers are a heat source.

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.
