Each channel has the following input fields:
Memory mode
Specifies the memory mode of the channel. Available options are ‘Internal’
(default) and ‘Extended’.
The Sample Rate of all the four Digital to Analog Converters (DAC) is
selectable between 53.76 GSa/s … 65 GSa/s. The Internal waveform memory
always operates at the sample rate. The Extended waveform memory can
operate at sample rate 53.76 GSa/s … 65 GSa/s or at one half of the sample
rate 26.88 GSa/s … 32.5 GSa/s or at one fourth of the sample rate 13.44
GSa/s … 16.25 GSa/s. The speed of operation of the extended memory is
adjustable using the parameter ‘Sample Rate Divider (extended memory)’.
Amplitude
Specifies the amplitude of the output signal.
Offset
Specifies the offset of the output signal.
Diff. Offset (Differential Offset)
Specifies the differential offset of the output signal.
V Term (Termination Voltage)
Specifies the termination voltage.
Output status indicator. This indicator reflects the color of the ‘Channel’ LED
on the front panel:
It is ‘OFF’ when the channel is disabled and no overload condition at this
channel has been detected.
It is ‘GREEN’ if the channel is enabled and no overload condition at this
channel has been detected.
It is ‘RED’ if the internal protection circuit of that channel has detected an
overload condition. Potential overload conditions are e.g. an external
short to GND or 50 Ohm termination to a wrong externally applied
termination voltage VTerm. In case an overload condition is detected,
remove the overload condition of the test set-up and enable the channel.
Output enable switch
If set to enabled position, the generated signal is present at the output.
FIR Scale
Shows the currently active scaling factor. This parameter can be adjusted in
the FIR filter tab.
Scaled Amplitude
Shows the effective output amplitude after the ‘FIR Scale’ had been applied.
