4-18 PRODIGIT
Please make sure the appropriate timer range before execute the load the PERI
LOW or HIGH command, otherwise the PERI load module will adjust to fit the Tlow
and Thigh ranges after programming the PERD LOW or HIGH command. The
engineering unit for PERI LOW and HIGH are
〝
ms
〞
.
Note:
1. There are four timer ranges in the Tlow / T high generator to produce a wide
period dynamic range, these ranges are adjusted by 3310 series load module
automatically which depends on the programmed Tlow / Thigh range.
2. For Example
：
The load CHA and CHIB USES the same T-high and T-low
controller of 3330A series electronic load.
Example:
PERI
：
LOW 0.125;PERI
：
HIGH 0.8
The above GPIB command set LOW / HIGH load duration's are 0.125 ms and 0.8
ms respectively.
RISE Time
Purpose
：
RISE load current slew rate setting.
Command Syntax
：
RISE{SP}{NR2}{NL}
Description
：
The RISE load current slew rate of load level change or dynamic load can be
programmed by RISE command. The RISE slew rate of 3310 series Electronic
Load module can be fully independent to the FALL slew rate.
The RISE load current slew rate data must include decimal point, otherwise this
command is unable to execute.
The effective RISE load current slew rate can be programmed is the sixth digit after
the decimal point. If the programming load current level over the maximum
specification at programmed range of 3310 series load module, the fastest RISE
slew rate will be sent to the load module.
Please make sure range I/II command before execute the load RISE slew rate
setting command, otherwise the 3310 series load module will adjust to fit the RISE
slew rate after programming the RISE command. The engineering unit for RISE
slew rate is
〝
A/us
〞
.
For Example
：
RISE 1.25 set RISE slew rate to 1.25 A/us.
FALL Time
Purpose
：
FALL load current slew rate setting.
Command Syntax
：
FALL{SP}{NR2}{NL}
