TL Series - For Easy Transient Programming
Extensive Transient Control1
With the addition of the remote control interface option, TL Series units
are capable of producing transients with a high degree of user program-
mability. Setting up transient programs is facilitated by a WindowsTM
Graphical User Interface program that allows amplitude, frequency and
event duration to be programmed from a PC. Time resolution is 1 ms
(0.001 sec) with a minimum time interval ranging from 1 to 40 ms, de-
pending on the transient type. Maximum transient time intervals are 9999
seconds. Transient programming allows the effects of common line dis-
turbances such as voltage surges, sags, drop-outs and frequency fluc-
tuations on the unit under test to be evaluated.
Drop transient causes output voltage to drop
to zero for a user specified period
Precision Measurements
For bench or automated test equipment (ATE) applications, the TL
Series can be ordered with the -OP1 option, offering both IEEE-488 and
RS232C remote control interfaces as well as extended measurements.
These measurements are available from the front panel and over the
bus. The TL Series uses closed-case calibration for both output and
measurement calibration, lowering cost of ownership.
SCPI Protocol Programming Commands
All functions of the TL Series are programmable over the available
IEEE-488 or RS232C interface. For example, the following tasks can be
performed over the bus:
· Set voltage to any level
Voltage Surge transient causes output
· Change frequency
voltage to surge. · Generate voltage dropouts, sags or surges
· Measure TRMS current, peak current, crest factor, TRMS voltage,
true power, apparent power and power factor
· Recall eight complete instrument setups from non-volatile memory
· Adjust current limit value
· Lock the front panel to prevent operator interference
· Switch between high and low voltage range
· Drop output voltage at specific phase angles for specified durations
