Control Voltage Input 

The BNC control voltage input 

In

 is connected to a differential amplifier to suppress common mode 

voltages between the external signal source and the amplifier (ground loops). Two jumpers (W2, W5) 
are provided on each amplifier module in order to adapt the control voltage input to the signal source.  
W5 connects the input signal reference via 100

 to the amplifier signal ground. W2 adjusts the 

amplifier gain to the output impedance of the signal source. 
 
 
W5  

 

1-2  Floating signal source  

Common mode voltage <1V

RMS

  

Default 

2-3  Grounded signal source (connected to PE)  

Common mode voltage <5V

RMS

 

 

 

 

 

W2  

 

1-2  Output impedance of signal source <1 

 Default 

2-3  Output impedance of signal source 50

Monitor Outputs 

Two BNC monitor outputs provide actual values of output voltage and output 
current, both of which are normalized to ±10 V.  
The voltage monitor output 

V Mon

 receives its signal via a compensated voltage 

divider and provides a scaled image of the output voltages. The frequency 
response is linear up to well above the upper cut-off frequency of the 
amplifiers. The frequency response of the 

I Mon 

current monitor output is 

limited to about 9kHz in order to filter out the common mode ripple of the 
internal high voltage sources. 
 
The monitor outputs are buffered (output impedance: 2k

) and short-circuit-proof. They are able to 

drive capacitive loads (coaxial cables), but are not designed to drive cables with a low-impedance 
termination.

Differential Output Mode 

Two amplifier modules can be configured to operate in a differential output mode. In this 
configuration, only amplifier 1 (Master) receives the input signal from the signal source. Amplifier 2 
(Slave) receives the input signal through the backplane of the subrack. The signal to amplifier 2 is 
inverted (180° phase shift in respect to amplifier 1).  
This mode can be used e. g. to differentially drive two deflection plates or to drive a floating load with 
up to 8000V
