94 Operation
Telnet Settings
The SR865A supports telnet connections. This can be Enabled or Disabled.
Choose Echo On/Off and the Receive/Transmit Terminators depending upon your host
software requirements.
Streaming Settings
The SR865A can stream output values continuously over the ethernet interface to a host
computer. It is the host computer's responsibility to keep up, there is no retry on dropped
packets.
Select the output {Channels} (X), (X and Y), (R and θ) or (X, Y, R and θ) and the desired
{Format} 32 bit Float or 16 bit Integer. Integers are scaled to the sensitivity.
The number of bits per sample point can range from 16 (X, integer) to 128 (XYRθ, float).
This has an impact on the network bandwidth necessary to maintain the stream.
The Sample Rate can be set to a fixed rate (1.25 MHz down to sub-millihertz). The total
bandwidth required is the sample rate times the number of bits per point. Note that
Sample Rate can change in response to changing the signal Time Constant. The Sync
filter, when engaged, can also modify the Sample Rate based on the signal frequency.
Choose the Packet Size to work with your host software.
The host Status is displayed.
