Hi everyone,
I am new in this forum and would like to start of by making a thread of a matter in which I need assistance.
I am in search of a used Agilent/HP 33120A arbitrary signal generator.
I have found quite a few for sale on the internet, but I need help on deciding which ones are in good working condition and are safe to buy.
When the signal generator powers up, it performs a "limited" self-test. There is also a more complete self test that can be done, by holding down the "SHIFT" button and then pressing the power on button.
But I believe this is not enough.
I have asked the sellers to also take some readings of the signal generators's output with an oscilloscope on the maximum available frequencies for each waveform type.
ie. sine wave at 15Mhz
square wave at 15 Mhz
Triangle wave at 100KHz (that is it's max freq.)
Have I done correctly??
Should I have some other test done?
It is not a cheap unit, so I want to make sure to get a good working unit and not a malfunctioning machine!!!!!
Someone please help me out here!!!!
PS. I have not specified at which voltages for which to test at.
Also I have not asked for testing of the waveforms at lower frequencies.
