(25) Set calibrator to 10 MHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (5) above. Calibrator Error display indication
will be within 5 percent.
(26) Set calibrator for a 1 V, 1 kHz wideband output.
(27) Adjust calibrator amplitude output adjustment controls until TI indication
equals TI indication recorded in (6) above, then press calibrator NEW REF key.
(28) Set calibrator to 10 MHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (6) above. If calibrator Error display
indication is not within 5 percent, perform b (4) below.
(29) Set calibrator to 1.5 MHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (6) above. Calibrator Error display indication
will be within 3 percent.
(30) Set calibrator to 990 kHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (6) above. Calibrator Error display indication
will be within 0.7 percent.
(31) Set calibrator to 190 kHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (6) above. Calibrator Error display indication
will be within 0.5 percent.
(32) Set calibrator for a 3 V, 1 kHz wideband output.
(33) Adjust calibrator amplitude output adjustment controls until TI indication
equals TI indication recorded in (7) above, then press calibrator NEW REF key.
(34) Set calibrator to 190 kHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (7) above. Calibrator Error display
indication will be within 0.5 percent.
(35) Set calibrator to 990 kHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (7) above. Calibrator Error display indication
will be within 0.7 percent.
(36) Set calibrator to 1.5 MHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (7) above. Calibrator Error display indication
will be within 3 percent.
(37) Set calibrator to 10 MHz and adjust amplitude output adjustment controls until
TI indication equals TI indication recorded in (7) above. Calibrator Error display indication
will be within 5 percent.
b. Adjustments
(1) Adjust calibrator amplitude output adjustment controls for a 0 percent Error
display indication and adjust C13 (fig. 1) until TI indication equals indication recorded
in a (3) above (R).
(2) Adjust calibrator amplitude output adjustment controls for a 0 percent Error
display indication and adjust C33 (fig. 1) until TI indication equals indication recorded in a
(4) above (R).
(3) Repeat a (9) through (16) above as necessary.
(4) Adjust calibrator amplitude output adjustment controls for a 0 percent Error
display indication and adjust R5 (fig. 1) until TI indication equals indication recorded in a
(6) above (R).
