Operating Instructions
- Turn the unit on at the top right hand corner.
- Connect a signal using the BNC connector A or B making sure that the switch is in the proper position.
- If you are using the amplifier in differential mode, make sure the switch is in the A-B position and two signals are inputted.
- Connect any output using either the 50 Ohms or 300 Ohms BNC connectors.
- Make sure the gain calibration knob is fully counter-clockwise and adjust the gain knob to the desired setting.
- The filter knobs represent a band pass filter where the outer knob is the upper frequency and the inner knob is the lower frequency.
- If the input signal exceeds the level indicated in the specifications, the overload light will go on. Use the recovery switch to reset the amplifier once the signal has been readjusted.
