Capabilities Description
Human Interface
This application has the primary use of verifying the presence of audio and making simple time-domain
measurements of the signal amplitude.
Primary Display Oscilloscope (voltage versus time)
Signal Acquisition
Input Channels High Resolution analog inputs
High Bandwidth analog inputs
Digital audio inputs
Inputs from the DSP connector
This application follows the primary input>
global SCPI parameter to determine which input to
display.
Oscilloscope Display
This display emulates a traditional digitizing oscilloscope, but with a touch-and-zoom touch screen
human interface.
Measurement Range Depends on the analog performance and digital
input word lengths
Display Appearance Both channels may be overlaid or put in a split-
window mode. Touch-and-zoom affects both chan-
nels in a window, and graticules track their signals.
Waveform Display Resolution Nominal 400 pixels vertical x 500 pixels horizontal
The reserved pixels for display will shrink during
generator control and programmed text display.
Display Update Rate Minimum of 15 screen updates per second with
proper triggering and time base conditions
Digitized Record Length
Amount of data in a waveform record obtainable
without missing samples.
Inputs with Sample Rates up to 48 kHz
Inputs with Sample Rates Above 48 kHz
Continuously variable from 32 to 48000 samples
per channel
Continuously variable from 32 samples to 4 milli-
seconds. All samples returned must be in the
vicinity of the trigger.
