Keysight 34950A User’s Guide 31
When set to ACTive the interrupt line will be driven by the module. The high
output voltage is set for both the handshaking and interrupt line on a bank with
the SOURce:DIGital:HANDshake:LEVel command.
When set to OCOLlector the interrupt line will be driven low, but will go to high
impedance mode when in the ‘High’ state. The open collector mode requires
external pull-ups.
The SENSe:DIGital:INTerrupt:MODE command sets the condition that will
cause the interrupt to be asserted. When set to MFULl the interrupt is given when
the memory is full. When set to COMPare the interrupt is asserted when the
pattern is detected (see page page 33). When either condition is removed, the
interrupt is de-asserted.
The interrupt line is enabled by the SENSe:DIGital:INTerrupt:ENABle
command and the status can be checked using the SCPI Status System (refer to
the Programmer's Reference Help file).
The settings for drive mode, output drive level, and input threshold also apply to
the bank’s handshake lines.
