The BenchTop™ Plus User Interface (part number PCI-820) includes all of the capabilities of the BenchTop™ Lite User Interface, plus five additional functions. These additional functions are Pulse Analysis, the ATL interpretive test language, Boundary Testing, Strip Chart, and FFT. The Pulse Analysis function calculates 19 parameters of a pulse or impulse waveform. The algorithms are patterned after those found in Standards developed by the IEEE. Each parameter can be individually selected for display. The Pulse Analysis function is useful for analyzing digital pulses found in telecom testing, oscillator testing, digital logic testing, and many other applications. Also, the impulse waveforms measured during power line disturbance tests (e.g. IEC 1000-2 and 1000-4) can be analyzed with the Pulse Analysis capability of BenchTop Plus.

Boundary Test, the third function included in BenchTop™ Plus, compares the acquired waveform to a set of upper and lower boundaries, and determines if the acquired waveform "passes" or "fails". The creation of the boundaries is easily accomplished using PCI Data Exchange, one of the programs included with the BenchTop Lite User Interface. BenchTop Plus includes the capability to count passes and failures, and take an appropriate action (e.g. store the waveform to a file) after each test. |
The second function is the Automatic Test Language
(ATL). ATL is an interpretive test language that provides the basic functions necessary to
create a test routine that can control instruments from PC Instruments and add-in cards
with register level descriptions. ATL is able to send and receive commands, display
messages, interpret test results, and store and recall information. ATL is intended for
test engineers that need to get a test system running quickly and do not want to invest a
large amount of time learning a programming language. Visual Basic and many third party
software packages (all of which are supported by PC Instruments...see the BenchCom™
data sheet for more information) provide more features and capabilities than ATL, although
they need a larger investment of time to learn. Strip Chart is the fourth function and is
more powerful than simply displaying the data in a "roll mode" or "strip
chart" mode. Instead of just plotting the raw data, BenchTop Plus has the power to
calculate a waveform parameter (e.g. RMS, Maximum, and Mean) and then plot the result of
the waveform parameter calculation on the strip chart. This function makes it possible for
monitoring a parameter of a high frequency waveform (e.g. peak-to-peak voltage) over a
long period of time, as well as displaying data in a traditional strip chart mode (simply
by displaying the average of a short sweep of data).
