11. Analog Output Accuracy Test
a. Performance Check
(1) Adjust signal generator frequency and amplitude controls for an output
frequency of 1000 MHz at 0 dBm (cw).
(2) Connect multimeter to CHANNEL A ANALOG OUTPUT on TI rear panel.
(3) Press TI keys as listed in (a) through (e) below:
(a) CW key.
(b) MENU key (two times).
(c) F1 key.
(d) 900 using number keys.
(e) Any UNITS key (nS or S or mS keys).
(4) Connect RF detector A to CALIBRATOR 1 GHZ output.
(5) Press keys as listed in (a) through (d) below:
(a) MENU key.
(b) F3 key.
(c) F1 key.
(d) Any UNITS key (nS or S or mS key).
(6) Disconnect RF detector A from CALIBRATOR 1 GHZ output.
(7) Connect RF detector A to signal generator RF OUTPUT.
(8) Adjust signal generator amplitude controls for an EL display indication between
-0.09 and +0.01 dBm.
(9) Record multimeter indication.
If multimeter indication is not greater than
-10 mV dc, perform b below.
(10) Adjust signal generator amplitude controls for an EL display indication of -9.98
and -10.02 dBm. Record multimeter indication.
(11) Subtract multimeter indication recorded in (9) above from multimeter indication
recorded in (10) above. If difference is not between -0.995 and -1.005 V dc, perform b below.
(12) Disconnect multimeter from CHANNEL A ANALOG OUTPUT on TI rear panel.
(13) Connect multimeter to CHANNEL B ANALOG OUTPUT on TI rear panel.
