RES:TLEVel Channel-Specific Resistance Command/Query
Description
This command specifies the value of the programmed resistance level for the TRANsient
input when the electronic load is in the CR (Constant-Resistance) Mode. When the
Transient Subsystem is on, the electronic load input resistance will switch (under control
of the Transient Subsystem) between the main resistance and TLEVel at a rate determined
by the present value of VOLT:SLEW (lowest resistance range) or by CURR:SLEW
(middle and high resistance ranges). In order for input resistance level switching to occur,
TLEVel must be programmed as follows:
Lowest range TLEVel > LEVel
Middle and highest ranges TLEVel < LEVel
If the above rules are not followed, no error is generated but transient switching will not
occur. If the main resistance is subsequently programmed to the proper level with respect
to TLEVel, switching will begin provided the TRANsient subsystem is on. If TLEVel is
programmed outside the specified range, an error is generated (See Table 4-2 at the end of
this chapter).
Command Syntax
RESistance:TLEVel <NRf+>
Parameters
See Table 4-1 and the Operating Manual of the electronic load model.
Value Coupling
The higher values of resistance levels have less resolution. Programmed levels are set to
the nearest value obtainable by the hardware.
Examples
RES: TLEV MAX Set transient level to maximum resistance for the range
RES:RANG 1000 Since TLEV> LEV on the 1k range, no
RES 200; :RES:TLEV 400; :TRAN ON transient switching occurs
RES: TLEV 100 Now TLEV < LEV and input switches from
100 to 200 ohms
Query Syntax
RES:TLEV?
Returned Parameters
<NR3> Transient resistance value for present range. If the electronic
load is not in Resistance Mode, the value will still be set, even if it is less
than the presently programmed input resistance.
