Agilent B2901/02/11/12A Precision Source/Measure Unit How to source continuous pulses without any measurement This material shows how to setup the instrument to source continuous pulses without any measurement using the B2901/02/11/12A, through example to source 2 V continuous pulses with the timing parameters such as 300 us pulse delay, 200 us pulse width and 500 us source trigger period. Figure 1 shows the timing chart for the continuous pulse source.

Timing chart for the continuous pulse source It is required to abort the instrument when you’d like to stop sourcing continuous pulses. This material also shows how to abort the instrument to stop continuous pulses. Setting up the pulse condition Step 1. Press source. to edit the source function, and then select (1) Press Mode to set the source function to the voltage (2) Press VOLTS (V) Agilent B2901/02/11/12A Precision Source/Measure Unit Step 2. Press to edit the source value, and then enter 0 V to set the source value to 0 V. (1) Press Source Step 3. Press (2) Enter Source Value to edit the limit value, and then enter 10 mA to set the limit value to 10 mA. (1) Press Limit Step 4. Press (2) Enter Limit Value to change the keys shown in Assist keys, and then press (1) Press Show Pulse Step 5. Press , then press (2) Pulse Sub-Panel appears to set the pulse source ON. After turning on the pulse source, you can see Source Shape which shows the pulse source mode. (1) Press ON to show Pulse Sub-Panel. Source Shape Agilent B2901/02/11/12A Precision Source/Measure Unit Step 6. Rotate to select Channel 1 Pulse Parameters and set them up as below. (Peak: 2 V, Delay: 300 us, Width: 200 us) Step 7. Press to show Trigger Sub-Panel. (1) Press Show Trigger Step 8. Press to edit the trigger type, and then select (1) Press (2) Trigger Sub-Panel appears to set the trigger type to MANUAL. (2) Press MANUAL Agilent B2901/02/11/12A Precision Source/Measure Unit Step 9. Rotate to select the source trigger period and press to edit it. Then enter 500 us to set the source trigger period to 500 us. (1) Rotate and press Source Trigger Period Step 10. Rotate to edit (2) Enter Source Trigger Period to select the source trigger source and press to edit it. Then press the source trigger source to TIMER. (1) Rotate and press Source Trigger Source to edit Step 11. If you aren’t on the top of the Function menu, press Step 12. Press (2) Press TIMER repeatedly to return to the top level.
