Constant Conductance Mode (CG)
Conductance Ranges: <0·01 to 1 A/V (1 mA/V resolution); <0·2 to 40 A/V (0·01 A/V
resolution).
Setting Accuracy: ± (0·5% + 2 digits + 30 mA).
Regulation: < 2% for 90% load power change (V > 2 Volts, using remote sense).
Temperature Coefficient: < (0·04% + 5 mA) per ºC.
Slew Rate Ranges: 1 A/V range: <0·1 A/V per s to >10 A/V per ms.
40 A/V range: <4 A/V per s to >400 A/V per ms.
Minimum transition time: 100 µs.
Constant Voltage Mode (CV)
Voltage Ranges:
V
min
to 8 V (1 mV resolution) and V
min
to 80 V (10 mV resolution).
V
min
depends on current: typically <2V at 80A
Setting Accuracy: ± (0·2% + 2 digits).
Regulation: < 30 mV for 90% load power change (using remote sense).
Temperature Coefficient: < (0·02% + 1 mV) per ºC.
Slew Rate Ranges: 8 V range: <0·8 V per s to >80 V per ms.
80 V range: <8 V per s to >800 V per ms.
Minimum transition time: 100 µs.
Constant Power Mode (CP)
Power Range: 0 to 320 Watts.
Setting Accuracy: ± (0·5% + 2 W).
Regulation: < 2% over 5 V to 75 V source voltage change (using remote sense).
Temperature Coefficient: < 0·1% per ºC.
Slew Rate Ranges: <32 W per s to >3200 W ms.
Minimum transition time: 100 µs.
TRANSIENT CONTROL
Transient Generator
Pulse Repetition Rate: Adjustable from 0·1Hz to 10kHz in 3 overlapping ranges.
Pulse Duty Cycle: 1% to 99% (percentage of period at Level B).
Setting Accuracy: Frequency: ± 2% of range; Duty Cycle: +2%
Slew Rate Control
The slew rate control applies to all changes of level whether caused by manual selection, remote
control or the transient generator.
The level change is a linear slew between the two level settings with a slope determined by a
three-position range switch and a single turn control. Read-out is in the units of the mode
selected; the range available in each mode is shown above.
Setting Accuracy: ± 10% ± minimum transition time (levels within 10% to 90% or range).
Level Variation: ± 5 digits
