Analog signal outputs are available in true differential or single-ended form for
one channel operation and single ended when operating in dual channel mode.
Output amplitudes are 1.0V peak-to-peak using the primary X1 amplifiers; 4.0V
peak-to-peak using the high-level X4 amplifiers. Offsets can be set to +/-3.5V
with 2 mV resolution.
In addition to the full bandwidth output, the DBS 2050A has three selectable low
pass output filters with cutoff frequencies of 200 MHz, 20 MHz and 2 MHz.
Other filter requirements are accommodated with available SMA feed-thru filter
modules.
The sampling clock is built around a precision phase detector capable of
synchronizing to internal or external references. The sample clock rate is
programmable over a range of 600 S/s to 2.4 GS/s. The external reference
input can range from 2.5 MHz to 100 MHz.
