The 3314A has amplitude and frequency calibration routines to insure that its per-
formance equals or exceeds the specifications listed in Table 1-1
the Service Manual.
A 3314A calibration loads new calibration constants into the internal
insure that the 3314A meets its specifications. In most cases, this requires a
measurement routine to generate new data. In cases where accurate correction
(
data is already available, the measurement cycle is not performed. Calibration
Disable and Enable refer to the measurement cycle, not the act of calibration.
CAlibrate All
A CAL ALL takes - 2 seconds to generate 29 amplitude and frequency calibration
constants. The following operations cause the 331 4A to completely calibrate itself
whether calibration measurements have been disabled or not:
-Power ON (also enables calibration measurements)
-PRESET or .. PR" (also enables calibration measurementsl
-CAL (BLUE shift RCL) (also enables calibration measurements)
-" CA" (does not enable calibration measurements)
