HIGH PERFORMANCE CAPTURE
The SCD5000 and SCD1000 are designed to capture low nanosecond and
picosecond single-shot events. Whether the application involves Laser, ESD, EMP, Accelerators or other high-speed single-shot phenomena, the
SCD series waveform recorders can capture the event with excellent
fidelity.
The maximum acquisition rate of 200 GS/s provides time resolution to 5
ps. With time windows from 5 ns to 100 µs, the SCD series recorders
provide flexible acquisition windows. When the delay line is used,
approximately 2.5 ns of pretrigger information can be captured.
The SCD5000 uses direct access with input sensitivity of 5 V and offset
of ±4.0 V. The SCD1000 provides quality conditioning of the input signal
with 100 mV to 10 V full scale ranges, dc offset and ac or dc coupling.
There are two input channels which can be configured to multiplex two
signals or algebraically add or subtract two input signals to the single
channel waveform recorder.
The waveform record length is selectable between 256, 512 or 1024 data
points. With 16 built-in waveform locations, multiple trigger events can
be stored into separate storage locations. Each record is time and date
stamped for later comparison. There are 10 nonvolatile settings storage
locations for quick instrument setup.
STAND-ALONE OR SYSTEM SUPPORT
The SCD Series recorders are designed for use in either a stand-alone or
a system environment. With the standard display unit, SCD waveform
recorders allow full control of operation, viewing of up to 4 waveforms
and cursor measurements.
In a system environment, there is a high-speed GPIB interface and
commands to make data acquisition flexible and fast.
OPTIONS EXPAND CAPABILITY
A fast waveform capture option (Opt, 1 P) increases the capture rate by
ten times, from one waveform per second to ten waveforms per second.
There is a choice of input connectors in addition to the the standard
Type-N connector. On the SCD1000, a choice of SMA or Tek Type II
intelligent probe interface are available. On the SCD5000, SMA
connectors can be chosen.
