Full-featured, PC-based Differential Oscilloscopes

The PCI-411 and PCI-412 Differential Input Oscilloscopes occupy one PC/AT
expansion slot and combine robust differential oscilloscope input
amplifiers with a powerful set of software to capture many
difficult-to-measure waveforms. Standard features of the PCI-411 and
PCI-412 are: 

* 1 MHz Bandwidth and Realtime Sample Rate of 
* 12.5 Megasamples/Second
* Common Mode Rejection Ratio of 80 dB at 100 Hz 
* Common Mode Range of +/- 40 Volts (PCI-412) 
* Input Protection of +/- 200 Volts 
* Input Impedance of 1 M-ohm and 15pF 
* AC/DC coupling and DC Offset Control 

The PCI-411 and PCI-412 provide wide bandwidth differential mode
measurements in a convenient-to-use PC-based oscilloscope. Each
oscilloscope board has a single channel. The PCI-411 has seven vertical
ranges from 10 mV/div to 1 V/div, while the PCI-412 has seven vertical
ranges from 50 mV/div to 5 V/div. The BenchCom software bundle, provided
with the PCI-411 and the PCI-412, includes the capability to control
several oscilloscopes in a multi-channel test system. 

Many demanding applications require differential measurement. As an
example, these oscilloscopes can be used to eliminate unwanted 50/60 Hz
when measuring the outputs of force sensors, bridges, accelerometers, and
strain gauges. Sensing current on motor control lines, SCRs, audio
signals, and power lines is easily accomplished using a shunt and the
differential inputs of these new oscilloscopes. Any waveform that is not
referenced to ground can be easily measured using the differential inputs
on the PCI-411 and PCI-412. Rotational velocity measurements can be
accomplished by combining a pick-up coil, the differential inputs, and the
frequency counting function provided with the BenchTop for Windows
Graphical User Interface. The input resistance and capacitance are
compatible with X10 and X100 probes thereby extending the common mode
measurement range. 

Data acquisition boards can handle easy measurements but if the measurement
demands a full featured oscilloscope, the PCI-411 and PCI412 provide the
measurement capability of a stand-alone oscilloscope with the convenience
of the PC environment. 

The PCI-411 and PCI-412 sell for $1495 and are available four weeks after
receipt of order.
