Operating Instructions—067-0599-00
output via its STEP GENERATOR switch. The
576's base sensing circuit is grounded. The
067-0599-00 sees only external loads in this
position.
STEP GEN
Routes the 576's Step Generator output to the
Calibration Fixture's EXTERNAL MONITOR
output via its STEP GENERATOR switch,
loading the 576's base sensing circuit.
10
Provides a 0.192 load for the 576's Step
Generator output for checking short circuit
current limiting.
40 V LOAD
Provides a 3.88 kQ load for the 576's Step
Generator output to test maximum voltage
output in the voltage mode.
COLL VOLTAGE + 10 INTO 1 MQ
Not Used.
EXTERNAL MONITOR, 1 V/STEP (INTO 10,000 MQ)
BNC connector providing output of the STEP
GENERATOR LOADS switch for external monitoring.
P819
3-pin plug connected to 75 Q load for the 576's CAMERA
POWER output.

OPERATING CONDITIONS
There are certain conditions that must be met before the
performance limits specified are valid.
The instrument must be calibrated at an ambient
temperature between +20°C and +30°C.
Remove the Standard Test Fixture from the Type 576
and install the 067-0599-00 Calibration Fixture plug-in
module. The 067-0599-00 is totally dependent on the Type
576 for AC line voltage and regulated low voltage power
supplies. :
Turn the Type 576 on and allow at least 10 minutes
warm-up time before making any checks or adjustments.
Because of the multiplicity and complexity of controls on
the 576 and 067-0599-00 Calibration Fixture, checking
and/or adjusting the 576 should be done sequentially
according to the Performance Check/Calibration Procedure
in the manual furnished with this calibration fixture
(Tektronix part number 070-1207-00).
Using the EXTERNAL MONITOR Output
When checking or adjusting the 576's Step Genertor out-
put, always monitor with a very high input impedance. The
067-0599-00 EXTERNAL MONITOR STEP GEN and EXT
ONLY outputs are 1 V/STEP into at least 10,000 MQ when
the STEP GENERATOR switch on the 067-0599-00 and the
STEP GENERATOR AMPLITUDE on the 576 are in match-
ing positions. Outputs from the rest of the STEP GENERA-
TOR LOADS switch are the results of the indicated loads to
the 576's circuits.
