Base Frequency
Select the base frequency. The default setting for the SS420x
is 10 Hz, which gives optimal signal to noise, and can be used
in countries using either 50Hz or 60Hz. The base frequencies
available will depend on the baud rate chosen. If the baud
rate is less than 38400bps, the base frequencies 100 and 120
will not be available. If you choose a higher base frequency,
you must select a base frequency that can be evenly divided
into your line frequency (i.e. 30 for 60Hz countries and 25 for
50Hz countries). If selected incorrectly, you may see line
frequency noise on your chromatogram. For best
performance, select a base frequency close to the maximum
sampling frequency you will be using to acquire data.
Sampling frequencies available in the Acquisition Setup
portion of the method will reflect the Base Frequency
selected.
Range
For each channel used, select the button next to the signal
range for the detector connected to that channel.
