a. Performance Check
(1) Press TI keys as listed in (a) through (c) below:
(a) INSTR PRESET.
(b) DATA 30.0.
(c) DATA SPCL.
(2) Reset calibrator.
(3) Connect calibrator WIDEBAND OUT to TI MODULATION OUTPUT/AUDIO
INPUT using cable and termination supplied with calibrator.
(4) Set calibrator for a wideband output frequency of 50 Hz at a level of 3 V.
(5) Press calibrator NEW REF key.
(6) If TI does not indicate within limits specified in first row of table 12, perform b below.
(7) Repeat technique of step (4) above, changing only the calibrator output
frequency to frequencies listed in table 12. If TI does not indicate within limits specified in
