Rev A 

7 

2.3.1.2 

Power Button 

The momentary POWER button turns the main power to the amplifier on and off.  The status of the green light-

emitting diode (LED) in the switch indicates whether the amplifier’s power is on or off.  The main power supply 

fans are active when power is on.  The LCD touch display is active as long as the main circuit breaker for the 

amplifier power entry module is on. 

2.3.1.3 

Adjust Knob 

The ADJUST knob is used to set the value of the RF Gain between 0 and 100 percent.  The ADJUST knob can 

be rotated both clockwise and counterclockwise 360 degrees. 

2.3.1.4 

Touch Screen 

The touch screen is a color LCD that can accept single touch events from soft blunt objects such as a human 

finger.   The mechanism that registers touch events is resistive based and relies on pressure not capacitance.  

Menu options presented on the touch screen are typically gray in color with a black text label in the center.  

When a valid touch event is registered a thin black box appears around the valid touch location and an optional 

audible beep will occur. 

2.3.1.5 

Remote Communications Ports 

The Remote option allows for control of the amplifier using GPIB, USB, Ethernet, Fiber-Optic (serial) or RS-

232 Serial ports located on the rear of the amplifier.   

2.3.1.6 

Interlocks  

The 3U MPC has one interlock circuit that is wired to the rear panel Safety Interlock connector. This interlock 

requires a normally closed external circuit to allow the unit to function. 

This interlock circuit inhibits RF amplification by disabling the low level (A1) and Power (A2 & A3) amplifier 

stages. 

The Inhibit Interlock is wired to the rear panel interlock connector pins 1 and 8. A closed circuit from interlock 

connector pin 1 to pin 8 is required for normal operation. Opening the Inhibit Interlock connection will inhibit 

the amplifier and display 

Fault:Interlock 

on the front panel Touch Display. 

When the Inhibit Interlock circuit is restored to a closed condition, the Inhibit Interlock fault can be cleared by 

pressing the 

RESET

 button on the front panel LCD or by using the remote reset command (when the Toggle 

Switch is set to 

REMOTE

).
