41-320
Dual PXI Waveform Digitizer Module
●14-Bit Dual Channel Digitizer
●Flexible Differential or Single Ended Input
●Internal, Selectable 50MHz and 70MHz
Clocks
●Selectable Filters to Reduce Out Of Band
Signals
●AC or DC Coupled Termination With
Adjustable DC Pedestal
●PXI Trigger Support for Synchronizing
Measurements
●512K Word Signal Capture Memory
●Excellent Dynamic Range
●LabView and LabWindows Libraries
The 41-320 Dual PXI Waveform Digitizer Module is a
high performance dual-channel 14-bit digitizer capable
of operating at sample rates of 70MHz. It has been
optimized for high performance and excellent SFDR.
This makes it an ideal tool for capturing analog signals
for digital analysis.
DUAL PXI WAVEFORM DIGITIZER
41-320
The digitizer has fully differential input terminals to
reduce the effects of external noise and common mode
signals found in typical test systems. The inputs can
also be set to single ended mode for operation in more
electrically quiet environments. The input impedance
can be set to 10kΩor 50Ωwith DC coupling. The 50Ω
setting can also be AC coupled to allow capture of
signals on a DC pedestal without an excessive input
current. Full scale input voltage can be switched in
ranges between 1 Volt and 25 Volt peak to peak.
For applications requiring the capture of a DC coupled
signal on a voltage pedestal the 41-320 can be
adjusted to have a DC offset applied to the input.
This ensures that the full resolution of the converter is
maintained.
The input to each digitizer can be filtered with a
30MHz, 15MHz or 6MHz low pass filter. This is to
restrict the impact of broad-band spurious signals
when capturing input signals containing lower
frequencies.
The module supports external trigger sources, star
triggering and PXI triggering. This allows synchronized
measurements to be performed in a PXI test system.
The 41-320 is supplied with easy to use soft front
panels and VISA kernel drivers
