PRELIMINARY PROCEDURE
1. Ensure that the correct nominal line selector block
has been installed on the line selector pins on the power
module interface board, and the regulating range selected
includes the applied line voltage. Refer to the installation
section of the power module manual.
2. Ensure that all test equipment is suitably adapted to
the applied line voltage.
PERFORMANCE CHECK PROCEDURE
1. Dial Alignment
a. Set the FG 501 controls as follows:
FUNCTION Triangle

Fully cw
OFFSET 2
Midrange and In
PHASE In
MULTIPLIER
10 3
FREQ VERNIER Fully cw
FREQUENCY Hz Near 10
3. Install the FG 501 into the power module and, if
applicable, install the TM 500-Series test equipment into
the test equipment power module.
4. Connect the equipment under test and the test
equipment to a suitable line voltage source. Turn on all
equipment and allow at least 20 minutes for the equipment
to stabilize.
'Below SN BJ30000 AMPL control Is labeled OUTPUT.
Tor SN below B130000 set OFFSET to zero.
b. Adjust the oscilloscope vertical for dc coupling at
2 V/div sensitivity. Set the time base sweep speed to
.1 ms/div. Set the triggering controls to internal
slope operation.
c. Connect the OUTPUT of the FG 501 through a 50 Ω
coaxial cable and a 50 Ω termination, with the 50 Ω
termination at the vertical input of the oscilloscope.
