*CLS
Clear status
Sets the status byte (STB), the standard event register (ESR) and the EVENt part of
the QUEStionable and the OPERation registers to zero. The command does not
alter the mask and transition parts of the registers. It clears the output buffer.
Usage: Setting only
*ESE <Value>
Event status enable
Sets the event status enable register to the specified value. The query returns the con-
tents of the event status enable register in decimal form.
Parameters:
<Value> Range: 0 to 255
*ESR?
Event status read
Returns the contents of the event status register in decimal form and then sets the reg-
ister to zero.
Return values:
<Contents> Range: 0 to 255
Usage: Query only
*IDN?
Returns the instrument identification.
Return values:
<ID> Rohde&Schwarz,<device type>,<order number>/<serial num-
ber>,<firmware version> <hardware version>
Example:
Rohde&Schwarz,LCX200,3629.8856k03/900020,02.018

Sets bit 0 in the event status register when all preceding commands have been execu-
ted. This bit can be used to initiate a service request. The query writes a "1" into the
output buffer when all preceding commands have been executed, which is useful for
command synchronization.
*RCL <Number>
Recall
Loads the instrument settings from an intermediate memory identified by the specified
number. The instrument settings can be saved to this memory using the command
*SAV with the associated number.
Manual operation:
See "Recall Settings from file..." on page 143
*RST
Reset
Sets the instrument to a defined default status. The default settings are indicated in the
description of commands.
Usage:
Setting only
Manual operation: See "Default Settings" on page 143
*SAV <Number>
Save
Stores the current instrument settings under the specified number in an intermediate
memory. The settings can be recalled using the command *RCL with the associated
number.
Manual operation:
See "Save Settings to file..." on page 143
*SRE <Contents>
Service requests enable
Sets the service request enable register to the indicated value. This command deter-
mines under which conditions a service request is triggered.
The query *SRE? returns a decimal value of the service request enable register which
corresponds to the binary-weighted sum of all bits.
Parameters:
<Contents> Contents of the service request enable register in decimal form.
Bit 6 (MSS mask bit) is always 0.
Range: 0 to 255

*STB?
Status byte query
Reads the contents of the status byte in decimal form.
Usage: Query only
*TRG
Trigger
Triggers all actions waiting for a trigger event. In particular, *TRG generates a manual
trigger signal. This common command complements the commands of the TRIGger
subsystem.
Usage:
Event
Manual operation: See "[Trig.]" on page 76
See "Measurement Mode" on page 81
*WAI
Wait to continue
Prevents servicing of the subsequent commands until all preceding commands have
been executed and all signals have settled (see also command synchronization and
*OPC).
Usage:
Event
11.4 Test signal commands
The following section describes the commands for setting the test signal and general
measurement parameters.
The value range of a specified parameter, e.g. frequency, current and voltage varies
depending on the settings of other measurement parameters. For the specified charac-
teristics, see the specifications document, section "Specifications" > "Effective mea-
surement ranges".
