2105 OPERATOR'S MANUAL – SECTION 6
When making adjustments:
Resistor: Increase or decrease resistance values
in increments of +/- 10%.
Capacitor: Incrementally increase capacitor val-
ues by a factor of 2 or 3.
After final adjustments have been made to the
circuit, the final waveform for your planned appli-
cation should be tested to confirm the amplifier's
compensation setting.

Remote Status and Control using
the SIM Interlock I/O Connector
The procedures outlined in this section assume
competence on the part of the reader in terms of
amplifier systems, electronic components, and
good electronic safety and working practices.
AE Techron 2105 amplifiers come with a SIM-BNC
input module that also contains a female, 25-pin
D-Sub connector. This connector can be used
to provide remote control and monitoring of the
amplifier.
The information provided here will instruct you in
the wiring of several control and status applica-
tions including:

Information subject to change
NOTE:
•
If possible, use 1% metal film resistors. AE
Techron discourages installation of potentiome-
ters in the resistor location of the compensation
circuit because this can decrease stability and
may increase inductance.
•
The parallel capacitor in the RC network serves
to increase stability but can be removed, if it is
not required for system stability. If the parallel
capacitor is used, it will usually decrease the
value of resistance needed.
•
In multiple amplifier systems, expect to decrease
the value of R63 in series systems by 1/2.
