Agilent Technologies 5951-2827, 5951-2826 manual Setting CR Values

Page 57

b.Press again and note that the display indicates "C:TLV 1.0000". Note that you can use the Input ENTRY keys to increment and decrement the transient current level. Operation is similar to that described above for the main current level.

Setting CR Values

The CR values are programmed by pressing the applicable FUNCTION keys and then setting the desired value using the ENTRY keys. The display identifies the selected function; for example, R:RNG identifies resistance range. See Appendix A for considerations regarding high-resistance applications.

Ranges

The resistance values can be programmed in a low, middle, or high range. The valid CR values that can be programmed are listed in Table 4-3 along with the applicable front panel key and display identifier. Note that all resistance levels are programmed in ohms and the slew rate is in amps/microsecond or volts/microsecond depending upon the resistance range.

1.In the middle and high ranges, the resolution of the main level and the transient level degrades as higher values are

entered. The value of resistance displayed will be the closest one to the value entered. A similar effect will occur with

the and keys. Refer to Appendix A for considerations regarding high resistance applications.

2.In the low resistance range, the resistance slew rate is programmed in volts/microsecond instead of in ohms/microsecond. Whatever value is programmed for the voltage slew rate (see "Setting CV Values") is also used for resistance in the low range. In the middle and high ranges, the resistance slew rate is programmed in amps/microsecond. Whatever value is programmed for the current slew rate (see "Setting CC Values") is also used for resistance in either the middle or high ranges.

3.In the low range, the transient resistance level must be set to a higher value than the main resistance value. In the middle and high ranges, the transient resistance level must be set to a lower value than the main resistance value.

Changing the programming range can cause the present CR settings to be automatically adjusted to fit within the new range. For example, assume that you are programming the Agilent 6060B 300 Watt Electronic Load, the present range is 1 to 1 k ohms "R:RNG 1000.0", and the present settings are:
