FEATURES
The Model
194A High Speed Voltmeter is a high speed DC
voltage sampling instrument suitable for a wide variety of
applications, including the analysis of laboratory
phenomenon, as well as the characterization of transient and
periodic waveforms.
The Model
194A can sample at rates up to 1MHz with 2 1/2
digit, 8-bit usable resolution, or up to 100kHz with 4 1/2
digit, 16-bit resolution. Each A/D channel has 64K bytes of
memory allowing up to 65,535 samples to be stored for later
analysis with one of the many Model
194A mathematical functions.
Key Model
194A features include:
• Autoranging—Autoranging allows the instrument to measure a
wide dynamic range of input signals.
• Zero—A zero feature allows a baseline signal level to be
subtracted from subsequent readings. The baseline can either
be taken from an applied signal, or keyed in from the front
panel or programmed over the IEEE-488 bus.
• Filtering—Internal analog filtering with selectable poles
of 50kHz or 500kHz is available to reduce the effects of noise.
• Math Functions—A number of mathematical functions
including average, integral, standard deviation, true RMS,
peak, and peak-to-peak are included with the instrument
software.
• Dual-channel Operation—Two separate, isolated A/D channels
are available with the optional Model
1944A A/D Module
installed.
• IEEE-488 Interface—A standard feature of the Model 194A
that allows the instrument to be controlled from a computer.
• Real Time Output—This port allows instrument data to be
transmitted to a computer or similar device at the sampling
rate via a user-supplied interface.
• Programmable Sampling Rates—The instrument can be
programmed to sample data as fast as 1MHz, or as slow as 1Hz.
• Programmable Number of Samples—The number of samples per
measurement sequence can be programmed to any value between
1 and 32,767 (16-bit resolution) or 1 and 65,535 (8-bit
resolution).
• Programmable Triggering—The instrument can be triggered
from the input signal, an external trigger signal, from the
other channel (when the Model
1944A option is installed), or
over the IEEE-488 bus. Programmable triggering parameters
include single or continuous modes, delay, slope, and level.
• XY Mode—Allows the instrument to drive external display
devices such as oscilloscopes and plotters. Internal
software allows easy generation of graphs from sampled data.
• Translator Mode—Simplifies IEEE-488 programming by
allowing the use of English-like syntax.
• External Sample Control—Allows sample collection to be
synchronized to external events
