8.12 Frequency Channels
Description
The Frequency Channels measure the frequency on their assigned input chan-
nel.
Input
Any Analog Input Channel. A voltage channel is recommended for best re-
sults.
Calculation
Frequency is measured over a multi-second time window to improve resolu-
tion and accuracy. The frequency measurement operates in a band that is ap-
proxi/-15% of the nominal frequency.
Triggers
• High & low magnitude
• Negative and positive rate of change
To prevent multiple triggers on threshold conditions, the frequency magnitude
triggers have a fixed 0.02 Hz hysteresis.
Recording
Low Speed: Frequency measurements at a rate of one value per cycle.
Number of
Channels

Notes
