2Mathematical Functions For Traces - R&S ESU Series Operating Manual

R&S ESU
DETECTOR The DETECTOR CISPR RMS softkey activates the CISPR rms detector.
CISPR RMS
Remote command:
DETECTOR The DETECTOR CISPR AV softkey activates the CISPR average detector.
CISPR AV
Remote command:
The DETECTOR CISPR RMS and DETECTOR CISPR AV softkeys are only avail-
able in zero span mode. The bandwidth is limited to the values 200 Hz, 9 kHz,
120 kHz and 1 MHz. In order to use the normal bandwidths again, the detector
must be changed, e.g. using AUTO SELECT.
4.8.8.2 Mathematical Functions for Traces
TRACE MATH
The TRACE MATH softkey opens a submenu in which the difference between the
selected trace to trace 1 is calculated. The softkey is highlighted if a math function is
activated.
T1-T2->T1 |
T1-T3->T1
TRACE POSITION
TRACE MATH OFF
T1-T2->T1 | The T1-T2 and T1-T3 softkeys subtract the corresponding traces. The result dis-
T1-T3->T1 played is referred to the zero point defined by TRACE POSITION.
To indicate that the trace has been obtained by subtraction, the difference "1 - 2" or
"1 - 3" is indicated on the trace info of trace 1 and in the TRACE main menu the
TRACE MATH softkey is highlighted.
Remote command:
TRACE The TRACE POSITION softkey activates the entry of the trace position for 0 differ-
POSITION ence. The position is stated in % of the diagram height.
The range of values extends from -100% to +200%
Remote command:
TRACE MATH The TRACE MATH OFF softkey switches the math function off.
