Hi, I am using the monitor output of a Model 425 Gaussmeter to measure an oscillating field with a DAQ and an associated optical signal via synchronized analog inputs. I am aware of the small deviations of the monitor signal in the absolute values, as described in sec. 5.3 of the manual. Is there possibly also a frequency-dependent time delay of the monitor signal and can it be specified? Many thanks for any advice! Andreas

Dear Andreas,
I am sorry for the delayed response. There may be a slight, very minimal delay, but we have not measured and specified it nor do we understand if the delay remains the same throughout the various measurements (AC or DC). If you're observing a delay in measurement, it could also be due to the settling time of the measurement signal. The entire measurement stage is AC-coupled to get rid of DC offsets.
Greetings,
Ogi K.

Hey Andreas ,Muneer here. I'm not personally familiar with the intricacies of the Model 425 Gaussmeter, but any frequency-dependent time delay in electronic instruments can be quite critical, especially when dealing with synchronized inputs. If it's not mentioned explicitly in the manual, I'd suggest reaching out directly to the manufacturer or checking any available technical bulletins. They might provide insights or corrections for such nuances. Always best to get info straight from the source! Hope you nail down the accuracy you're aiming for. All the best! Cheers, Muneer |
