R&S ESU
Characteristics: *RST value: 1
SCPI: device-specific
Mode: R, A
CALCulate<1|2>:LIMit<1...8>:STATe ON | OFF
This command switches on or off the limit check for the selected limit line.
The result of the limit check can be queried with CALCulate<1|2>:LIMit<1...8>:FAIL?.
Up to 8 limit lines can be defined at the same time. The numeric suffixes <1|2> of CALCulate indicate
the measurement window.
Example:
"CALC:LIM:STAT ON"
'Switches on the limit check for limit line 1 in screen A.
"CALC2:LIM:STAT OFF"
'Switches off the limit check for limit line 1 in screen B.
Characteristics: *RST value: OFF
SCPI: conform
Mode: R, A
CALCulate<1|2>:LIMit<1 to 8>:UNIT AMPere | DB | DBM | DBMV | DBMV_MHZ | DBPT | DBPT_MHZ
| DBPW | DBPW_MHZ | DBUA | DBUA_M | DBUA_MHZ | DBUA_MMHZ | DBUV | DBUV_M |
DBUV_MHZ | DBUV_MMHZ | DBV | DEG | HZ | PCT | RAD | S | UNITLESS | VOLT | WATT
This command defines the unit for the associated limit line.
The definition is valid regardless of the measurement window.
DBxx_MHZ indicates the units dBxx/MHz and DBxx_MMHZ indicates the units dBxx/mMHz (the
measured level is referenced to a 1 MHz bandwidth).
Specification of the DB unit automatically switches the limit line over to relative mode. Units other than
DB cause the limit line to switch over to absolute mode.
Example:
"CALC:LIM4:UNIT DBUV"
'Sets the unit of limit line 4 to dBµV.
Characteristics: *RST value: DBM
SCPI: device-specific
Mode: R, A
CALCulate<1|2>:LIMit<1...8>:FAIL?
This command queries the result of the limit check of the limit line. It should be noted that a complete
sweep must have been performed for obtaining a valid result. A synchronization with *OPC, *OPC? or
*WAI should therefore be provided.
Up to 8 limit lines can be defined at the same time. The numeric suffixes <1|2> of CALCulate indicate
the measurement window. The result of the limit check responds with 0 for PASS, 1 for FAIL, and 2 for
MARGIN.
In receiver mode, this command is not available.
Example:
"INIT;*WAI"
'Starts a new sweep and waits for its end.
"CALC2:LIM3:FAIL?"
'Queries the result of the check for limit line 3 in screen B.
