SUPPLEMENTARY
PERFORMANCE CHECK PROCEDURE
General
This procedure provides a method of checking those
electrical characteristics not checked in the Performance
Check procedure. It is expected that this procedure will be
used when it is desired to perform a complete performance
check of the instrument. The procedure may be used as a
continuation of the performance check procedure, or as a
separate procedure.
Instructions for using the Record and Index, Table 2-6,
and for setting controls, are given at the beginning of this
section.
Equipment Required
The following equipment and electrical components are
required to perform this procedure.
1. Test Oscilloscope-See the description in item 4 of
the Equipment Required list for the adjustment procedure
(X1 probe not required).
2. 10
M~
resistor, 1/4 watt, 5%; 1
M~
resistor, 1/4
watt, 5%.
3. Two 12 inch patch cords with standard banana plugs.
4. BNC male to dual binding post adapter. See item 5 of
the Equipment Required list for the performance check
procedure.

Performance Check-Type 576
Preliminary Supplementary Performance Check
Procedure
1. If this procedure is being performed following the
performance check procedure, go to step 5.
2. Set the Line Voltage Selector assembly switches and
the 60 Hz-50 Hz switch on the Type 576 rear panel in
accordance with the line voltage source to be used.
3. Connect the Type 576 to the line voltage source.
4. Turn on the Type 576 and allow at least 5 minutes
warmup at an ambient temperature between 0°C and
+50°C (+32°F and +122°F) before making any checks.
5. Set the controls as shown at the beginning of the
procedure and start the supplementary performance check
procedure with step 1.
