function, the indicated function is performed during the sweep with the math function used in
place of a detector. The trace operands for the math function are set using the Trace Operands key.

Remote Command

Notes

The lower level menu, which contains an embedded 1-of-N, does not auto-return when a
selection is made.

Notes

The Trace Math Function command has 6 main set of parameters:

- Set 1 defines the “result trace”:

-Set 2 defines the “function”:

PDIFference|PSUM|LOFFset|LDIFference|OFF

- Set 3 is a “trace operand” (1):

- Set 4 is a “trace operand” (2):

- Set 5 defines the “Log Offset” (in dB).

- Set 6 defines the “Log Difference Reference” (in dBm).

Note that the trace math mode is an enumeration; that is, when a math function is set for a
trace it turns off any math function that is on for that trace and sets the new math function.

The parameters sent in the command are reflected in the values in the softkey menu. There is
no default for any parameter; all 6 parameters must be sent to satisfy the parser. Failure to
specify a parameter will result in a missing parameter message.

Note that for some of the math modes some of the parameters are not relevant. For those modes,
the parameters are ignored, and sending “,,” is sufficient for those parameters.

The query returns the math mode, the operand traces, the offset and the reference for the
specified trace, all separated by commas. The return value of irrelevant parameters is undefined;
empty fields (“,,”) would be desirable.

Remote command examples are included in each section below.

Dependencies

Trace Math is not available if Normalize is on.

Trace Math is not available if Signal ID is on.

None of the trace operands can be the destination trace. If any of the three trace math
commands is sent with a destination trace number matching one of the operands a warning is
generated and the function does not turn on.
