This question concerns the 33120A Function Generator. I am having trouble selecting a Burst Count and Burst Rate.
On POR, the unit defaults to 1 kHz and 100 mVpp. That is all ok for this question.
I then select Shift-Burst-Shift-Left arrow (Burst Count is displayed). Select the down arrow to get the parameter. I use the knob to select 12 cycles. I then select ENTER. I get TWO beeps. The display returns to the frequency with BURST displayed. On a scope, I get 12 cycles at a repetition rate of 20 ms. That's ok. Now, I want to change the count to 20. As before, I select Shift-Burst-Shift-Left arrow (Burst Count is displayed). Select the down arrow to get the parameter (12 is displayed from before). I use the knob to select 20 cycles. I press ENTER and get ONE beep and the display returns to the frequency without BURST being displayed. On a scope, I get a continuous sine wave of 1.0 kHz. I go through the process again (20 is displayed). I press ENTER and get TWO beeps and the frequency display along with BURST. On a scope, I get 20 cycles at a repetition rate of 30 ms.
Please notice the ONE and TWO beeps. The same problem (1 and 2 beeps) occurs when I want to change the Burst Rate.
AM I doing something wrong? Is the instrument OK? I am awaiting your response. Please help. Thanks, Justin If possible, please respond to me at firstname.lastname@example.org. Thanks.
