9. High Frequency Response
a. Performance Check
NOTE
Press FUNCTION FILT IN/OUT pushbutton to IN for
frequencies <10 kHz and to OUT for frequencies >10 kHz.
(1) Connect calibrator OUTPUT HI and LO to TI INPUT.
(2) Press and release all front panel pushbuttons to the out position, except
POWER.
(3) Set calibrator for a 1 mV, 1 kHz output. TI will indicate between 0.98 and 1.02
mV. Record TI indication.
(4) Set calibrator for a 10 mV, 1 kHz output. TI will indicate between 9.9 and 10.1
mV. Record TI indication.
(5) Set calibrator for a 100 mV, 1 kHz output. TI will indicate between 99.5 and
100.5 mV. Record TI indication.
(6) Set calibrator for a 1 V, 1 kHz output. TI will indicate between 0.995 and 1.005
V. Record TI indication.
(7) Set calibrator for a 3 V, 1 kHz output. TI will indicate between 2.985 and 3.015
V. Record TI indication.
(8) Connect calibrator WIDEBAND output to TI INPUT using calibrator
wideband cable and 50Ω feedthrough termination.
(9) Set calibrator for a 1 mV, 1 kHz wideband output.
(10) Adjust calibrator amplitude output adjustment controls until TI indication
equals TI indication recorded in (3) above, then press calibrator NEW REF key.
(11) Set calibrator to 10 MHz and adjust amplitude output adjustment controls
until TI indication equals indication recorded in (3) above. If calibrator Error display
indication is not within 5 percent, perform b(1) below.
(12) Set calibrator to 1.5 MHz and adjust amplitude output adjustment controls
until TI indication equals indication recorded in (3) above. Calibrator Error display
indication will be within 4 percent.
(13) Repeat (12) above at 990 kHz and 190 kHz.
(14) Set calibrator for a 10 mV, 1 kHz wideband output.
(15) Adjust calibrator amplitude output adjustment controls until TI indication
equals TI indication recorded in (4) above, then press calibrator NEW REF key.
(16) Set calibrator to 10 MHz and adjust amplitude output adjustment controls
until TI indication equals TI indication recorded in (4) above. If calibrator Error display
indication is not within 5 percent, perform b(2) and (3) below.
