Chapter 4, Description of Fields

Fields

Gate Time

This field specifies how long the decoder analyzes a signal after it has been triggered. The longer the gate time, the greater the number of bits analyzed.

Operating Considerations

If the gate is too long, the decoder’s data buffer becomes full. A message is displayed instructing you to decrease the gate time.

This function is not used with the NAMPS/NTACS RVC decoder.

Gain Cntl

AF Analyzer Gain Control specifies whether the AF Analyzer’s gain settings are controlled automatically by AF autoranging (Auto), or by manual control (Hold).

The following settings are affected by AF autoranging:

Input Gain

De-Emp Gain

Notch Gain

Operating Considerations

The normal mode of operation for the Gain Cntl field is Auto, allowing the instrument to adjust the AF gain settings for optimum measurement accuracy.

This field can be set to Hold to disable the autoranging routines to increase measurement speed. However, this requires you to select the desired gain settings manually for each measurement.
