if the trace is the target of a Copy or participant in an Exchange

–

if the trace is cleared using Clear Trace

Inactive traces that are also being displayed (traces in View) are displayed at half

intensity. Traces in View display across the entire X-Axis of the instrument. Their

horizontal placement does not change, even if X-Axis settings subsequently are

changed, although Y-Axis settings do affect the vertical placement of data.

When a trace becomes active (Update=ON), the trace is cleared, the average count is

reset, and a new sweep is initiated.

Note that putting a trace into Display=OFF and/or Update=OFF does not restart the

sweep and does not restart Averaging or Hold functions for any traces.

3.5.15.3 Math

Lets you turn on and configure Trace Math functions.

Math Function

Trace Math functions perform mathematical operations between traces and, in

some cases, user-specified offsets. When in a Trace Math 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 "Operand 1 /

Operand 2" on page 1750 controls.

For Swept SA Measurement (in SA Mode):

:CALCulate:MATH <trace_num>, PDIFference | PSUM | LOFFset | LDIFference |

OFF, <trace_num>, <trace_num>, <real>,<real>

:CALCulate:MATH? <trace_num>

where <trace_num> is any one of:

For all other measurements:

:CALCulate:<meas>:MATH <trace_num>, PDIFference | PSUM | LOFFset |
