Front Panel Controls and Indicators

Ready Indicators: Two green LEDs illuminate when the amplifier is initialized and ready to produce output.

Signal Indicators: Six green LEDs indicate the amplifier’s input and output signal levels.

Clip Indicators: Two Red LEDs illuminate when the channel’s output signal is nearing the onset of clipping.

Thermal Indicators: Two Red LEDs illuminate when the channel is nearing levels of thermal stress or overload that will cause the channel to shut down.

Fault Indicators: Not implemented.

DC Protect Indicator: The DC Protect Indicator signals that the amplifier has been placed in temporary Stand-by mode due to detection of a duty cycle that is outside of amplifier tolerance. The amplifier will remain in Standby mode momentarily, and then return to operation.

HF Protect Indicator: The HF Protect Indicator signals that the amplifier has been placed in temporary Stand-by mode due to one of the following high-frequency conditions: open load, oscillations, or high-frequency signals outside of amplifier tolerance. The amplifier will remain in Standby mode momentarily, and then return to operation mode.

Power Indicator: Blue LED indicates amplifier has been turned on and AC power is available. The LED will flash when the AC line voltage is 15% above or 25% below the nominal rated value.

Power Switch: Blue LED; indicates amplifier has been turned on and AC power is available. The LED will flash when the AC line voltage is 15% above or 25% below the nominal rated value.

Back Panel Controls and Connectors

Power Cord Connector: Standard 15-amp IEC inlet. Voltage is indicated above IEC inlet.

Reset Switch: Resets the circuit breaker that protects the power supply.

Output Connectors:One two-pole, 15-mm clamping terminal strip; accepts up to AWG 6 wire.

Signal Input Connectors:
  Balanced:Balanced BNC input connector accepts Twinax cable terminated with matching male balanced BNC connector. The Balanced Signal Input Connector can accept signal of up to +/- 10 Volts. Signals presented to this input will have a transconductance (current gain) of 20.
  Unbalanced:Unbalanced BNC input connector accepts Coax cable terminated with matching male unbalanced BNC connector. The Unbalanced Signal Input Connector can accept signal of up to +/- 10 volts. Signals presented to this input will have a transconductance (current gain) of 20.

Current Monitor Output: Unbalanced BNC output connector accepts Coax cable terminated with matching male unbalanced BNC connector. 1 volt / 10 amps.

Command vs. Actual (CVA) Comparator Output:Unbalanced BNC output connector generates a voltage signal that is proportional to difference between input (voltage command) signals and the resulting amplifier (current) output. 1 volt per 1 amp of difference between commanded and actual amplifier current output. Useful for viewing settling time (including propagation delay) and making final compensation adjustments.

Voltage Monitor Output: Unbalanced BNC output connector accepts Coax cable terminated with matching male unbalanced BNC connector. 1 volt / 10 volts.

Control Logic Connector:Female DB15 15-pin connector. Accepts serial (RS232) cable terminated with male DB15 connector. Provides methods for Force to Standby, Monitor Standby, Current Monitor, Voltage Monitor, CVA Comparator
