Ranges

Resistance may be programmed in any of three overlapping ranges (low, middle, high). The range can be set at the front

panel (, , and ENTRY keys) or via the GPIB (RES:RANG command). Any value in the low range selects the low range. Any value that is within the middle range and above the maximum low-range value selects the middle range. Any value that is within the high range and above the maximum middle-range value selects the high range. Note that the values of the present resistance settings may be automatically adjusted to fit within the new range.

Immediate Resistance Level

The resistance level can be set at the front panel ( and ENTRY keys) or via the GPIB (RES command). If the CR mode is the active mode, the new setting immediately changes the input at a rate determined by the voltage or current slew setting (see description below). If the module is not in the CR mode, the new setting is saved for use when the mode is changed to CR.

Triggered Resistance Level

The resistance level can be preset (stored in the Electronic Load) allowing the input to be updated when a trigger is received instead of immediately as described above. The resistance level can only be preset via the GPIB (RES:TRIG command). The preset capability is not available at the front panel.

If the CR mode is the active mode, the preset resistance level will become the actual value and the input will be updated when a trigger occurs. If the CR mode is not the active mode, the preset resistance level will become the actual value when a trigger occurs but there will be no effect on the input until the CR mode becomes active. Once a level is triggered, subsequent triggers will have no effect on the input unless another CURR:TRIG command is sent.

Transient Resistance Level

The transient resistance level can be set at the front panel ( , and ENTRY keys) or via the GPIB

(RES:TLEV command). The transient level and the main level are used in transient operation, which is described later in this chapter. In the low resistance range, the transient level must be set to a higher resistance value than the main level. However, in the middle and high resistance ranges, the transient level must be set to a lower resistance value than the main level.

Slew Rate

Slew rate in resistance mode is not programmed in ohms/second. In the low resistance range, slew rate is programmed in volts/second. Whatever value is programmed for the voltage slew rate is also used for the low resistance range.

In the middle and high resistance ranges, slew rate is programmed in amps/second. Whatever value is programmed for the current slew rate is also used for the middle or high resistance ranges.

Constant Voltage (CV) Mode

In this mode, the module will attempt to sink enough current to control the source voltage to the programmed value (see Figure 2-4). The module acts as a shunt voltage regulator when operating in the CV mode. The CV mode can be set

at the front panel ( , and keys) or via the GPIB (MODE:VOLT command). The CV mode parameters are described in the following paragraphs.
