5) PRE-FILTER AMPLIFICATION COLUMN

PC: The Initial Gain field displays the pre-filter amplification of the input signal. A few

orders of magnitude are allowed. The setting can be typed in, or the spinner buttons

can be used to scroll through the values. Any changes made are immediately

applied to the CyberAmp channel, and the Total Gain field is also updated.

Macintosh: The PreAmp column displays the pre-filter amplification valuesof the input signals.

Clicking on a field in this column brings up a list of available order-of-magnitude

values. Any changes made are immediately applied to the CyberAmp channel, and

the Total Gain field is also updated.

6) OFFSET COLUMN

PC: The DC Offset field displays the offset applied to the input signal. This field is

directly editable, or the spinner buttons can be used to change the value to the next

decade.

Macintosh: The Offset column displays the offset for each input channel. To edit the offset,

double-click on the item to be edited, and type in the desired offset into the dialog

box. To modify the offset units, highlight the field you would like to change, go to

the Cyber menu and select Offset Units. A dialog box is displayed, wherethe first

field contains a conversion factor, and the second contains units. For example, a

valid input would be 1 mV = 10 pA. The conversion factor can be negative, and a

real number such as 1 mV = 0.5 pA. The second two fields define how far the value

should be changed when <Command Up-Arrow> or <Command Down-Arrow> are

pressed.

7) LOW-PASS FILTER COLUMN

PC: The Lowpass Filter field displays the frequencies of the low-pass Bessel filter of the

CyberAmp amplifier. A predefined list of values are allowed. The setting can be

typed in, or the spinner buttons can be used to scroll through the values. The

Bypass checkbox below the field will disable the filter.

Macintosh: The LPF columns display the frequencies of the low-pass Bessel filter of the

CyberAmp amplifier. Clicking on a field in the low-pass filter column pops up a

list of available filter settings. The off setting is used to bypass the filter.

8) NOTCH FILTER

PC: The Notch Filter check box will enable a notch filter, which should be tuned to the

local line frequency, and is set to 60 Hz by default.

Macintosh: The Notch column displays the notch filter settings of all channels. The notch filter

should be tuned to the local line frequencey, and is set to 60 Hz by default. The

notch filter of any channel can be turned on or off by clicking on its field.
