If a service request has been generated,
SRQ
is displayed to the right of the up and down arrows. You
can instruct the instrument to generate a service request (SRQ) when one or more events or
conditions occur. This indicator stays on until the serial poll byte is read or all the conditions that
caused SRQ are cleared.
Active buffer indicator
The Active Buffer indicator shows the name of the active reading buffer. Select the indicator to open a
menu of available buffers. Select a buffer name in the list to make it the active reading buffer. The
name of the new active reading buffer is updated in the indicator bar.
The green bar next to the buffer name indicates how full the buffer is.
