Main Functions of the SL1400
Automated Measurement of Waveform Parameters
Section 11.5, "Automated Measurement of Waveform Parameters" in the user's manual
This function automatically measures parameters such as the maximum waveform level and frequency. There are 29 wave-
form parameters (including the delay between channels). Up to 24 parameters can be displayed on the screen. A total of up
to 48000 data values can be stored for all waveforms.
Delay parameter
(1 parameter)
Parameter concerning the time difference
from the reference waveform or trigger
point to the rising or falling edge of the
target waveform (delay between channels)
Time-axis parameters
(12 parameters)
Vertical-axis parameters
(12 parameters)
Other parameters
(4 parameters)
Statistical Processing
Section 11.6, "Performing Statistical Processing" in the user's manual
Statistical processing for the following five items can be performed on the same three measurement parameters as those of
the automated measurement of waveform parameters.
Maximum value (Max), minimum value (Min), average (Avg), standard deviation (Sdv), and the number of mea-
sured values used in the statistical processing (Cnt).
Parameters and values of the statistical processing targets
Measurement range
Statistical processing results
Max: Maximum value
Min: Minimum value
Avg: Average value
Sdv: Standard deviation
Cnt: Number of measured values used
in the statistical processing
The following three statistical processing modes are available.
Cyclic statistical processing (measurement and statistical processing per cycle)
Measures the selected parameters on the waveform per cycle from the left end to the right end
of the screen (from the oldest waveform).
Normal statistical processing
Measures the selected parameters on all acquired waveforms while acquiring waveforms and
performs statistical processing.
Statistical processing of history data
Measures the selected parameters on the history waveform and performs statistical
processing. Measurement and statistical processing are performed from the oldest data.
A list of measured values used in the cyclic statistical processing and statistical processing of the history data can be dis-
played.
Acquisition Memory Backup
Section 7.7, "Backing Up the Acquisition Memory" in the user's manual.
This function protects the data in the acquisition memory from sudden power failures.
Turn ON the ACQ MEMORY BACKUP switch on the right side panel to protect the data in the acquisition memory even when
the power supply is cut off. The data held in the acquisition memory immediately before the power is turned OFF is backed
up. Alkaline dry cells or nickel hydride rechargeable batteries (four AAA batteries) are required for the backup.
