DATAMAN 520 series oscilloscope with rollmode
User’s Guide
defines the ARM condition for the “E” input. If it is set to “0” the data acquisition will
be interrupted if the “E” input is connected to log. 1. If it is set to 1, log.0 interrupts
the data acquisition.
If there are several ARM inputs set to active state, every active condition must be met
to allow data acquisition.
TIP: Internal 10 kOhm pull-up resistor is connected between “E” input and 3.3V
power supply of the oscilloscope. This sets log.1 to unconnected input. This
condition can be used for simple data acquisition control. If only the E arming
condition is active and set to 1, grounding the “E” input interrupts the data
acquisition. If the condition is set to 0, grounding the “E” input starts the data
acquisition.
The “ARM” indicator changes its color under following conditions:
- it is red, if the data acquisition is not started (and triggered) yet
- it is yellow, if the data acquisition has started already, but it is interrupted by ARM-
ing system
- it is green if the data acquisition is in progress.
