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.
