|
|
Example: |
SYST:COMM:GPIB:ADDR 10 Set the GPIB address to 10. *RST; SYST:COMM:GPIB:ADDR? After a reset, the address is maintained (the response is 10).
|
Sets the receive terminator of the analyzer. The receive terminator indicates the end of a command or a data block.
The receive terminator setting is relevant if block data is transferred to the analyzer (FORMat[:DATA] REAL). In the default setting LFEOI, the analyzer recognizes an LF character sequence with or without the EOI control bus message as a receive terminator. An accidental LF in a data block can be recognized as a terminator and cause an interruption of the data transfer.
The EOI setting is especially important if commands are transferred in block data format, because it ensures that the parser for command decoding is activated by the terminator only after the command has been completely transferred. Readout of binary data does not require a change of the receive terminator.
|
LFEoi |
LF character sequence with or without EOI recognized
|
|
EOI |
EOI recognized only
|
|
*RST value |
LFEoi.

Defines the block size for the data transfer between the instrument hardware and the software. The bock size has an impact on the display of traces and on the readout of trace data using the commands of the TRACe... or CALCulate<Chn>:DATA... subsystems.
|
ALL |
Data transfer with full buffer size. The data for each sweep are transferred together so that each displayed trace contains the data of exactly one sweep. The same is true for queried trace data. The trace is displayed or updated at once, the sweep progress is not visible on the screen.
|
|
AUTO |
Data transfer with an automatically determined block size. In general the data blocks comprise only part of a trace, therefore the sweep progress is visible on the screen. On the other hand the displayed trace can show the results of two consecutive sweeps.
|

Initiates an immediate update of the channel or trace settings.
The command has an effect if the analyzer operates in single sweep mode (INITiate<Ch>:CONTinuous OFF) and if the display update is switched off (SYSTem:DISPlay:UPDate OFF). In this scenario, a change of the channel or trace settings is usually not taken into account immediately. The analyzer waits until the end of the current sweep sequence and changes all settings made during the last sweep period when the next single sweep sequence is initiated. Several settings can be made en bloc, which generally saves time.
SYSTem:SETtings:UPDate ONCE causes the analyzer to apply the settings at once without waiting for the end of the current single sweep sequence. The command has no effect in continuous sweep mode or if the display update is switched on.
The settings are also updated when the continuous
sweep mode is activated (INITiate<Ch>:CONTinuous
ON).
