11.8 Setup panel
The top section of this panel has controls for the conversion rate for the 32 parallel analog to
digital converters (ADCs) and the number of conversions that are averaged into each sample.
The sample rate is the ADC rate divided by the conversions per sample number.
Figure 30. Setup ADC and range control.
The ADC rate can be set between 2000 Hz and 1 MHz. Usually it is best to use a high ADC rate
and reduce the sample rate as necessary by increasing the number of conversions per sample, as
this improves the resolution and signal to noise ratio. The value can be set between 6 and 65535
in internal and buffered modes. In sweep mode it is set automatically to 1.
The full scale current range can be set to 10 mA, 1 mA, 100 µA or 10 µA. The setting applies to
all thirty-two channels. A future firmware release will allow the range to be adjusted
individually for pairs of channels.
Figure 31. Current range selections.
The remainder of the setup controls are presented on three sub-panels, covering triggering and
acquisition modes, channel gain settings and other controls. Below is a Save Configuration
button which will save the acquisition parameters to non-volatile memory and the F3200E will
recall the configuration when it powers up.
