The GX3748 has 48 front input channels, divide into 3 groups 16 channels each. The first group has two programmable voltage comparators to detect window condition, the other two groups have only one programmable voltage competitor. Input threshold voltages can be 0-50V. At any time the user can measure the voltage on any of the 48 input channels. Up to 4 channels can be selected to perform digital capture on a subset with timestamp. The capture memory records any voltage change according to the window/threshold and the time it took place. Each channel has a pull-up / pull-down 10KOhm resistors that can be connected. Each of the3 input groups has a dedicated digitizer each with 12-bit resolution. All 3 digitizer inputs have the same programmable sample period and can record up 87,300 samples, the number of samples to acquire are set programmatically. Each of the digitizer inputs can have a programmable trigger mode and trigger threshold. Acquisition progress and total number of samples acquired of each of the digitizer inputs can monitor at any time.
Monitor the voltage level of each 48 front input channels.
Detect if front Group 0 input channels 0-15 are within a configurable voltage window, directly or against a previously set minimal assertion duration.
Detect if front Group 1 input channels 0-15 are above a configurable voltage threshold, direct or duration.
Detect if front Group 2 input channels 0-15 are above a configurable voltage threshold, direct or duration.
Perform digital capture of up to 3 channels (one form each group) with timestamp.
Enable pull-up / pull-down resistors on each front input channel.
Each of the3 input groups has a dedicated digitizer each with 12-bit resolution.
All 3 digitizer inputs have the same programmable sample period and can record up 87,300 samples, the number of samples to acquired are set programmatically.
Samples rate is common to all three channels, sample rate can be set as follows (in uSec): 2,4,8,16,32, 64, 128, 256.
Each of the digitizer inputs can have a programmable trigger mode. User can set programmatically the trigger mode for each channel : level high, level low, rising edge, falling edge.
Each of the digitizer inputs can have a programmable trigger threshold (0-48V).
Acquisition progress and total number of samples acquired of each of the digitizer inputs can monitor at any time.
User can read the raw data for each channel (in voltages).
Pulse analysis: Rise Time, Fall Time, Width and Amplitude.
