Revision 3.1 August 7, 2014
ENGINEERING UNITS – The amplitude units of the signal
may be set to PEAK, PEAK to PEAK, or RMS using the drop
down menu selector.
FREQUENCY UNITS – Use the drop down tool to select either
Hz (hertz or cycles per second), RPM (Revolutions per Minute)
or RATIO.
FREQUENCY – Enter the desired frequency setting for the
signal. The frequency may be in Hertz (Hz) or a ratio of the
Channel A frequency. When RATIO is selected, this window is
used to designate the ratio value. A value greater than 1.000
will produce a signal frequency greater than Channel A, while a
value of less than 1.0000 will produce a lower frequency.
AMPLITUDE – Enter the desired amplitude value (see
ENGINEERING UNITS Above) of the signal.
ODD CYCLE AMPLITUDE – When in TACH mode, the
amplitude of the “odd” signal is expressed as a percentage
of the other signals. Less than 100% for a “short” tooth
and greater than 100% for “long” tooth signals.
TOOTH COUNT – When operating in TACH mode, multi-tooth
speed signals may be simulated. This value represents the total
number of teeth in the speed signal including the odd tooth.
