F1 Output voltage range
The VDS 200Q10.x has a fixed output range of -60V to +60V.
F3 Amplifier Gain
The VDS200Q10.x generators offer 2 different GAIN setting:
x1:
limits the output voltage to +/-10V
x7:
limits the output voltage to +/-60V (full range)
F5 Current limitation mode
Different to other VDS200Qx.y units (e.g. VDS200Q50.2), the current limitation of the VDS 200Q10.x is
limited to Peak OFF. There is no inrush current you get on top of the RMS current limiter.
Peak OFF: This selection enables no inrush current above what is set. The current limit circuitry will start
immediately.
F7 Frequency Compensation
The VDS 200Q10.x support three frequency ranges,
Std:
Standard. This is the normal operating mode with a good compromise between stability and
bandwidth. The bandwidth in this selection is approximately 40 kHz.
Capa:
Capacitive. This mode is specifically designed for capacitive and/or reactive loads. This reduced
bandwidth, high stability mode is perfect for use during normal transient testing, conducted sine wave
(CSW) testing. The bandwidth in this mode is limited to approximately 3 kHz. This is the default
startup mode, and is still fast enough for most common pulses like Pulse 4 and 2b.
HF:
This mode is for testing where high bandwidths are required. This mode allows frequencies up to
180kHz.
CAUTION:
As with all fast amplifiers, the user should monitor the DUT to ensure no ringing or
excessive over- shoot is present that could result in damage to the DUT or couplers. In case
there is a question the Capacitive mode should be used.
