1.4.10 SRQs
When the N4865A receives a Reverse Channel Service Request, it sends a
device_readstb
RPC to the companion oscilloscope to obtain the Status Register
response and assert the GPIB SRQ signal. The SRQ signal is deasserted when
the N4865A is Serial Polled or when the N4865A learns that the companion
oscilloscope has deasserted its MSS bit.
1.4.11 Serial Poll Responses.
The N4865A periodically reads the companion oscilloscope's Status Byte
Register and use the response to update its Status Byte. The oscilloscope
polling rate is 3 Hz.
