I have been using my U1602 in the auto run mode to observe and capture signals on the fly.
When I try to use the 'SINGLE / NORM' trigger mode to capture a turn on trace I am unable to do so. The o'scope will not trigger.
I have tried changing all the various functions, trigger type, coupling, levels, slope, even changing the trace position on the screen, nothing so far has produced a triggered trace. 'SINGLE / NORM' or 'RUN / NORM' mode.
Firmware version is: 2.5.5 (as rc'vd, not upgraded)
I'm using the Agilent 1:1 o'scope lead.
I've tried triggering on a one volt DC signal and a 1 volt AC sine wave with no effect.
Any suggestions would be greatly appreciated,
Roland

When we needed a portable o'scope at work a model U1604A was purchased, primarily because it offered quick data transfer via the USB storage port. (Not included on the U1602A version)
The o'scope was purchased for use in product timing. We are looking at an AC or DC voltage developed across a current shunt. Approximately 100 mVolts.
Basically the product was to be placed across a DC constant current source, power applied and the scope triggered by the voltage developed across the current shunt. The timing function would proceed for approximately 60 seconds, in which time the product would time out, breaking the current path. Simple enough. The information would be captured on the o'scope and the data saved for transfer to an Excel spreadsheet.
The main requirement for the U1604A was the ability to trigger on the rising DC voltage from the current shunt. This it can readily do, as long as you don't require anything slower than a 20 mSec/div sweep speed.
Anything slower than 20 mSec/div and the o'scope automatically changes to the Roll Mode (see Agilent User's and Service Guide, page 70). Think chart recorder.
Initially Agilent indicated that the o'scope could be triggered at any sweep speed, but after they actually tried it, they admitted that it could not be done.
No joy, as the triggering is limited to 20mSec/div or faster. Their recommendation was that anything 50 mSec/div or slower we would have to use the Roll mode and use the Run/Stop button to pause the trace.
