Pulse Width Accuracy

This test verifies that the transient generator pulse width accuracy is within specification. Note: Use the GPIB controller to generate a continuous pulse train.

1.Connect Electronic Load, Power Source, Current Probe and Oscilloscope as shown in figure B-5.

2.If using a controller, connect controller to Electronic Load mainframe rear panel GPIB connector.

3.Turn on the Electronic Load and press [Recall]. Scroll to until *RST is displayed and press [Enter].

4.Turn on the Power Source and program the voltage to 10 V and the current to 15 A.

5.Turn on the Oscilloscope and set to:

a.Ch 1 vertical deflection, 15 mV/div.

b.1:1 probe, DC coupled, 50 Ohms.

c.Position or offset to 50mV.

d.Horizontal time base to 20 uS/div.

e.Trigger on positive edge at about 50mV.

6.Turn on Current Probe to the 10mV/A position.

7.Run the following program for a continuous pulse train or skip to step 8 to manually generate pulses.

10 OUTPUT 705;”*RST”

20 OUTPUT 705;”TRAN:MODE PULS”

30 OUTPUT 705;”CURR:TLEV 10”

40 OUTPUT 705;”TRAN:TWID 100E-6”

50 OUTPUT 705;”TRAN ON”

60 OUTPUT 705;”TRIG:IMM”

70 WAIT 1000 ! wait 1 second

80 GOTO 60 ! loop back to line 60 to for continuous pulse train.

90 END

8.For front panel single pulse operation: (Note: skip to step 9 if using a controller to generate a continuous pulse train)

a.Press [Current] and scroll to C:TLEV. On the Entry keypad press 10 [Enter].

b.Press [Tran] and scroll to T:TWID. On the Entry keypad enter 1E-4 then [Enter] to generate a pulse width of 100uS.

c.Press [Tran] and scroll to T:MODE. On the Entry keypad scroll to T:MODE PULS then press [Enter] .

d.Press [Tran]. Using the Entry keypad scroll to ON and press [Enter] to activate the transient mode.

e.Press [Trigger Control] and then [Enter] to initiate the trigger system.

f.Press [Shift] and then [Trigger] to generate a single current pulse from zero to 10 A..

9.Adjust the oscilloscope as needed to display a complete pulse waveform. Generate pulses as needed.

10.Measure width of the 10 A, 100 uS nominal pulse between the 50% points of waveform and record the results on Performance Test Record. Note: Use the built-in measurement capabilities of the oscilloscope, if available, for the most accurate results.
