(10) Set calibrator frequency to 200 Hz and set TI for a carrier frequency of 200 Hz
by pressing ENTRY [FREQ] [2] [0] [0] and [Hz] pushbuttons. TI will indicate 00.00
(0.4) dBm.
(11) Repeat technique of (10) above for 10 and 15 kHz. TI will indicate 00.00 (0.4) dBm.
NOTE
In the following checks the TI bandwidth may be changed to
either 400 Hz or 3100 Hz. However, if 20 Hz bandwidth is
desired, TI carrier frequency can be fine tuned by utilizing TI
COUNTER and FREQUENCY TUNE functions.
(12) Repeat technique of (10) above for 25, 100, and 500 kHz, and 1.0 MHz. TI will
indicate 00.00 (0.2) dBm.
(13) Disconnect calibrator from TI.
(14) Connect calibrator wideband to multimeter INPUT terminals. Set multimeter
for ac voltage measurements and press calibrator WBND pushbutton.
(15) Set calibrator for an initial 0.273861 V, 1 kHz wideband output. Adjust
calibrator for a multimeter indication equal to value recorded in (1) above ( 5 digits).
(16) Press calibrator NEW REF pushbutton; then set to STBY.
50 pf
(17) Remove wideband output from multimeter and connect to TI 10 k
connector. Set calibrator OPR/STBY to OPR.
(18) Press TI ENTRY [FREQ] [1] [kHz] pushbuttons (pause until an internal CAL
cycle is completed).
(19) Set calibrator frequency to 2 MHz and set TI for a carrier frequency of 2 MHz by
pressing ENTRY [FREQ] [2] [MHz] pushbuttons. TI will indicate 00.00 (0.2) dBm.
(20) Repeat technique of (19) above for 15 MHz. TI will indicate 00.00 (0.2) dBm.
(21) Repeat technique of (19) above for 20 MHz. TI will indicate 00.00 (0.25) dBm.
b. Adjustments. No adjustments can be made.
13. Half Power Bandwidth
a. Performance Check
(1) Press TI pushbuttons as listed in (a) through (c) below:
(a) [RECALL] [0] and AUTO CAL off.
(b) [RECALL] [.], [CNTR FREQ], and [7].
(c) MEASUREMENT/ENTRY [OFFSET], ENTRY
[RDNG
OFFSET],
FREQUENCY TUNE [AUTO], and BANDWIDTH [20 Hz].
