Rohde & Schwarz ZVL series - Retrieving Measurement Results

R&S ZVL Programming Examples
Basic Tasks

// 2. Start single sweep, use *OPC?
// If *OPC follows INITiate<Ch>[:IMMediate], it places a 1 into the output queue when the sweep is
terminated.
// An appropriate condition in the remote control program must cause the controller to wait until *OPC?
returns one.
// The controller is stopped from the moment when the condition is set.
INITiate1:IMMediate; *OPC? // Start single sweep in channel no. 1, indicate the end of the
sweep by a 1 in the output queue.
// So far the controller may still send messages to other devices on the GPIB bus.
<Condition OPC=1> // Stop the controller until *OPC? returns one (program syntax depends
on your programming environment).
<Continue program sequence>
//
// 3. Start single sweep, use *OPC
// If *OPC follows INITiate<Ch>[:IMMediate], it sets the OPC bit in the ESR after the sweep is
terminated.
// This event can be polled or used to trigger a service request of the analyzer.
// The advantage of *OPC synchronization is that both the controller and the analyzer can continue
// processing commands while the sweep is in progress.
*SRE 32 / Enable a service request for the ESR
*ESE 1 / Set event enable bit for operation complete bit
INITiate1::IMMediate; *OPC // Start single sweep in channel no. 1, set the OPC bit in the ESR
after the sweep is terminated.
// The controller may still send messages, the analyzer continues to parse and execute commands.
<Wait for service request> // Controller waits for service request from the analyzer (program
syntax depends on your programming environment).
<Continue program sequence>
Retrieving Measurement Results
Programming task: Read the results acquired in a single sweep.
//
// 1. Read single values (-> Markers)
// Markers are the most convenient tool for determining and retrieving single values on traces.
// The analyzer provides up to ten markers; see Markers and Limit Lines.
//
// 2. Read complete trace
// Select a trace format and read formatted trace data.
