4. Operating Instruction
4.1 Function operation guide
86
The trace operation will be executed with [
Math
] submenu in the [More1/2 ▶ ] menu by pressing 【 Trace 】
key on the front panel. Specific steps are as follows.
Step 1. Select the trace corresponding to the Operand through [Operand1
▶
] Select menu:
Select any trace among Trace 1 to Trace 6 by pressing [Operand 2
▶
] menu; if the trace selected is not active,
the Series Signal Analyzer will automatically activate this trace.
Step 2. Select the trace corresponding to the Operand through [Operand2 ▶ ] menu:
Select any trace among Trace 1 to Trace 6 by pressing [Operand 2
▶
] menu; if the trace selected is not active,
the Series Signal Analyzer will automatically activate this trace.
Step 3. Execute trace addition:
When the [Op1+Op2->Op2] menu is pressed, the Series Signal Analyzer will automatically activate the trace
operation and carry out addition operation to the trace corresponding to Operator 1 and the trace
corresponding to Operator 2 and then save the results to the trace corresponding to Operator 2.
Step 4. Execute trace subtraction:
When the [Op1-Op2->Op2] menu is pressed, the Series Signal Analyzer will automatically activate the trace
operation and carry out the subtraction operation to the trace corresponding to Operator 1 and the trace
corresponding to Operator 2 and then save the results to the trace corresponding to Operator 2.
Step 5. Change operational rules:
When the [
Mode
▶
] menu is pressed, the data type of two traces in the operation will be changed. Operational
rules are logarithmic by default.
Step 6. Close trace operation:
When the [OFF] menu is pressed, the Series Signal Analyzer will close the trace operation.
Caution
The operation results can only be obtained by executing sweep measurement. During process of trace
operation, clearing trace, uploading trace and copying trace from file will affect the results of trace operation,
so those operations should be avoid.
8) Understand the relation of trace processing and trace operation
The trace operation is the mathematical operation carried out to the current active traces (any two traces from
6 ones) during one sweep, while the trace processing is to average or hold the traces obtained during many
sweeps. Whenever the trace operation function is enabled, operational rules are changed or operator selected
is changed, the trace data saving operation results will be cleared and the sweep measurement will be re-
executed.
After the trace is obtained, execute trace operation, then trace processing and save the processing results to
new trace for display or that transferred to the users through programmable interface. The specific relation is
shown in Fig. 4.4.
