hello,
i want to sample DC current, settings are internal trigger source (with a preset level) 5 kSa per trigger, i varied the sample timing, but essentially i want to sample at the highest rate possible (40 usec or 20 usec) and set the pre trigger samples to 1000. but i am not getting any data from before the trigger level is reached. i use the newest firmware on the 34470a (it's brand new) and benchvue 3.0 pro dmm.
any ideas?
jan

Are you expecting 6000 total samples? The 1000 pretriggers would be included in the 5000 total samples. In fact, if the trigger condition is met before 1000 samples have occurred, the total could be less. If you can, check the time stamp against when you actually generated the pre-triggers and see if it is in fact getting the pretrigger samples.
