8 Displaying the Trend of the Measured Values of
Waveform Parameters per Cycle
Procedure
• To exit the menu during operation, press ESC located
above the soft keys.
• In the procedural explanation below, the term
jog shuttle & SELECT refers to the operation of
selecting/setting items and entering values using the jog
shuttle , SELECT and RESET keys. For details on the
operation using the jog shuttle, SELECT, and RESET, see
sections 4.1 or 4.2 in the
DL7440/DL7480 User’s Manual .
• For a description of the operation using a USB keyboard or
a USB mouse, see section 4.3 in the DL7440/DL7480

The following setup or procedure is required to display the trend.
• Turn ON the assignment of the power analysis parameters to the computation
waveform. For the setup procedure, see section 3 in this manual.
• Display the target waveform on which to compute/display the trend.
• Set and execute the measurement of waveform parameters per cycle. For the
procedure, see section 10.7 in the
DL7440/DL7480 User’s Manual IM701450-01E.
To execute the measurement of waveform parameters per cycle, stop waveform
acquisition.
• Turn ON the computed waveform display. For the setup procedure, see section
9.1 in the DL7440/DL7480 User’s Manual.
Note
• The setup procedures for computed waveform Math1 are described below. Perform similar
steps for Math2.
• For the procedure for turning ON/OFF the computed waveform display (Math1 Display or
Math2 Display) and the procedure for setting computed waveform labels (Math1 Label or
Math2 Label), see section 9.1 in the
DL7440/DL7480 User’s Manual .
• To make correct measurements and computation, it is recommended that the difference in
the transfer time of the analyzed signals be corrected (deskewed). For the setup procedure,
see section 4 in this manual.
1. Press MATH . The MATH menu appears.
You can also display the MATH menu by selecting To Math in the Power Analyze
Setup dialog box described in section 3 of this manual and pressing SELECT.
2. Press the Math Mode soft key to select Normal. The normal computation menu opens.
3. Press the Math1 Setup soft key. The Math1 Setup dialog box opens.
* For the setup procedure of Math1 Display, see section 9.1 in the DL7440/DL7480
User’s Manual .
4. Use jog shuttle & SELECT to set Trend in the Operation box.
When the Math1 Setup dialog box is closed by pressing ESC or another key, the
specified equation appears in the Math1 Setup menu column.
