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