6 RLC Swept SA Measurement Front-Panel & SCPI Reference
Trace/Detector
The values of the operand trace points are assumed to be in decibel units (as they are internally
stored) and the reference is in dBm so the result is in dBm.
Example: If the first operand trace 1 is at 5 dBm, the second operand trace 2 is at –5 dBm, and
the reference is –25 dBm, then the destination trace will be –15 dBm.
Example: If the first operand trace1 is at 60 dBuV, the second operand trace 2 is at 50 dBuV, and
the reference is 35 dBuV, then the destination trace will be 45 dBuV.
See "More Information" on page 1369 .
Key Path Trace/Detector, Math
Example :CALC:MATH TRACE1, LDIF, TRACE4, TRACE5, , –6.00
Sets Trace 1 to Log Diff trace math function, sets the First Trace operand (for Trace 1) to Trace
4, sets the Second Trace operand (for Trace 1) to Trace 5, and sets the Log Difference reference
for Trace 1 to –6 dBm.
Couplings Selecting a math mode other than Off for a trace (pressing the key or sending the equivalent
SCPI command) puts the trace in View (Update On and Display On), even if that math mode
was already selected.
State Saved The Log Difference reference value for each trace is saved in instrument state
Min Same as reference level
Max Same as reference level
Default Unit depends on the current selected Y axis unit
Initial S/W Revision Prior to A.02.00
More Information
If a point in FirstTrace is equal to maxtracevalue, the resultant point is also maxtracevalue.
If a point in FirstTrace is equal to mintracevalue, the resultant point is also mintracevalue.
If neither of the above is true for a given point, then:
•
If that point in SecondTrace is equal to maxtracevalue, the resultant point is mintracevalue.
•
If that point in SecondTrace is equal to mintracevalue, the resultant point is maxtracevalue.
Off
Turns off Trace Math.
