b. Adjustments.
(1) Set calibrator output for an initial 1.000V, 1kHZ wideband output. Adjust
calibrator for TI indication equal to the value recorded in table 3 for 1.000V, 1kHz,
to establish a 1 kHz reference. Press calibrator NEW REF pushbutton.
(2) Set calibrator frequency to 10 MHz and adjust A3C33 fig. 2 for value
recorded in table 3 for 1.000V, 1 kHz. Repeat steps 8 a (5) through (7) above (R).
