• Because the waveform data stored in the acquisition memory is used to display waveforms on the screen, the
data of all sub channels is displayed as if though it were sampled at the same timing.
• The following operations are performed on the waveform data stored in the acquisition memory: waveform
zooming, cursor measurement, the automated measurement of waveform parameters, computation, FFT,
waveform searches, and the loading and saving of waveform data.
• GO/NO-GO determination and the display and searching of history waveforms are not performed on sub
channels.
• When you execute auto setup on the 16-CH voltage input module, sub channel on/off settings and settings
that relate to the horizontal axis (Time/Div, Record Time) are not changed.
• Wire all the L input terminals for all the sub channels on the same module to the same potential. The L input
terminals of all sub channels are common. Because the L input terminals are electrically connected inside the
instrument, connecting different potentials to them could result in short circuiting and damage to the 16-CH
voltage input module.
For information about the terminal arrangement, see section 2.18 in the
Getting Started Guide
, IM DL350-
03EN.
• For information about attaching and removing the terminal block and connecting and removing wires from the
terminal block, see section 2.18 in the

Notes about Using the 16-CH Temperature/Voltage Input Module (720221)
In comparison with normal temperature modules, which can receive input from two thermocouples, the 16-
CH Temperature/Voltage Input Module has sub channels that enable it to receive input from 16 thermocouples
through a scanner box. You can also measure the voltage of 16 channels. The 16-CH Temperature/Voltage Input
Module samples the measured sub channels in order.
• The 16-CH temperature/voltage input module uses only the odd main channels of the slot that it is inserted
into. It cannot use the slot’s even main channels.
• If you do not want to measure an individual sub channel, turn its input coupling off. Sampled data is not
acquired for channels whose input coupling is turned off.
• Regardless of the number of measured sub channels, the actual maximum sample rate is 100 kS/s. The rate
at which data is written to the acquisition memory varies depending on the main channel sample rate. For
details on the rate at which data is written to the acquisition memory, see appendix 2 in the
Getting Started
Guide
, IM DL350-03EN.
• The sample rate that is displayed on the screen is the sample rate of the main channel.
• Record length of each sub channel ≤ set record length/16
• The timing of waveform acquisition is different for each sub channel, but all the sub channels are stored in the
acquisition memory as if they had been sampled at the same timing. This means that the sampling times of
the acquired waveform data are different from the sampling times of the actual applied waveforms.
• Because the waveform data stored in the acquisition memory is used to display waveforms on the screen, the
data of all sub channels is displayed as if though it were sampled at the same timing.
• The waveforms displayed on the screen are updated at the set
regardless of the number
of measured sub channels. The previous value is stored repeatedly in acquisition memory until the value
changes. Saved waveform data is treated in the same manner.
• The following operations are performed on the waveform data stored in the acquisition memory: waveform
zooming, cursor measurement, the automated measurement of waveform parameters, computation, FFT,
waveform searches, and the loading and saving of waveform data.
• GO/NO-GO determination and the display and searching of history waveforms are not performed on sub
channels.
• When you execute auto setup on the 16-CH voltage input module, sub channel on/off settings and settings
that relate to the horizontal axis (Time/Div, Record Time) are not changed.
• Connect the 16-CH temperature/voltage input module to the scanner box with a cable and then connect
a thermocouple to the scanner box to perform temperature measurements. For information about how to
connect thermocouples to the scanner box’s terminal block, see section 2.19 in the Getting Started Guide, IM
DL350-03EN.
