Setting Tachometer Pulse Inputs
The LX-120 equips two of the tachometer pulse input channels in separate analog input channels. Their
input connectors are located on the rear panel.
Either 16 bits or 32 bits mode can be selected. When you select the 16 bits mode for one channel, another
channel is automatically effective at 16 bits mode. In 32 bits mode, you may select only one channel.
However, if 24bits A/D is specified, 16 bits mode cannot be specified.
See Section 6 for the specifications.
■ 1 x 16 bits tachometer pulse input channel is equivalent to 1 x analog input channel. 1 x 32 bits
tachometer pulse input channel is equivalent to 2 x analog input channels. Therefore, if you turn ON
tachometer pulse input channel(s), in order to keep the same analog input channels, it is necessary to
reduce the sampling frequency by following the setting of tachometer pulse input channel(s).
■ Set Moving Average to [1] only, when the sampling frequency of 102.4 kHz, 100 kHz, 96 kHz, 65.536
kHz, 51.2 kHz, 50 kHz, 48 kHz, or 32.768 kHz is selected.
■ Only 1 x 32 bits tachometer pulse input can be selected when the sampling frequency of 102.4 kHz, 100
kHz, 96 kHz, or 65.536 kHz is selected.
■ The LX Navi cannot monitor the tachometer pulse input in wave form display. Use the digital display to
monitor. (Refer to page 5-17)
■ The LX cannot playback the recorded tachometer pulse input signals. Process the data as a digital data
file.
■ You cannot use the tachometer pulse input channels and the generator output function at the same time.
