AMETEK SLM Series Rev B - Manual (Page 59)

SLM-Series AC/DC Electronic Load GPIB/RS-232 Programming Operation
M540072-01 Rev B 4-17
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 SLM-Series DC electronic load modules can be
fully independent from the FALL slew rate.
The RISE load current slew rate data must include a decimal point, otherwise this command
is will not execute.
The value for the RISE load current slew rate can be programmed up to sixth place after the
decimal point. If the programming load current level is over the maximum specification at the
programmed range of SLM DC series load module, the fastest RISE slew rate will be sent to
the load module. Please verify the range 1/2 command before execute the load RISE slew
rate setting command, otherwise the 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."
Example:
RISE 1.25 set RISE slew rate to 1.25 A/us.
FALL Time
Purpose:
FALL load current slew rate setting.
Command Syntax:
SLM DC Modules:
FALL{SP}{NR2}{NL}
Description:
Programs the FALL load current slew rate of load level change or dynamic load. The FALL
slew rate of SLM DC electronic load modules can be fully independent of the RISE slew
rate.
The FALL load current slew rate data must include a decimal point, otherwise this command
will not execute. The value for FALL load current slew rate can be programmed up to the
sixth place after the decimal point. If the programming load FALL slew rate is over the full-
scale specification, the fastest FALL slew rate will be sent to the load module. Please verify
the range 1/2 command before executing the load FALL slew rate setting command,
otherwise, the load module will adjust to fit the FALL slew rate after programming the FALL
command.
The engineering unit for FALL slew rate is “A/
μs”.
Example:
FALL 0.124 set FALL slew rate to 0.124 A/
μs.
SLEW Rate
Purpose:
Set the load current slew rate of SLD-series electronic load module.
Command Syntax:
SLD Modules:
SLEW{SP}{NR2}{;|NL}
Description:
Rise and Fall slew rate is the same for the SLEW command setting of SLD electronic load
module.
The Slew rate has two ranges, and it follows the CC mode range change automatically:
when CC Dynamic mode is in Range 1, the slew rate is in Range 1, if CC Dynamic mode is
in Range 2, then Slew rate is in Range 2.
