Parts Names and Functions of CF-4700
CF-4700 FFT Comparator
(3)
OVER: OVER indicator
Lit in red when the signal that is input to the input terminal mounted on the rear panel of the CF-4700 FFT
comparator exceeds the voltage level of 95% of the full scale.
(4)
PHONE: Headphone output jack
Used to connect headphones. This is a stereo mini jack (3.5 φ ).
By adding an optional CF-0473
amplitude modulation component extraction function
, signals which have passed
through the filter (LPF or HPF) can be heard as a sound from the stereo headphones.
!
CAUTION
• Connect stereo type headphones to PHONE (headphone terminal). However, the signal is actually output monaurally (same
L/R signals).
!
WARNING
• Installation of the ferrite core (for EMC)
Be sure to install the ferrite core (E04SR200932 by Seiwa Electric) that comes with the CF-0473 amplitude modulation
component extraction function to the stereo headphone cable. This is necessary to conform to the EMC directives.

DATA: Mass storage connector
This connector is dedicated to a mass storage connector.
If the optional CF-0477 USB mass storage function is added, a USB mass storage corresponding to a mass
storage class can be connected and accordingly a personal computer (PC) can be connected.
Connecting the PC enables the data in the CF-4700 FFT comparator to be sent to the PC.
(6)
USB: USB connector (type A)
USB2.0 connector used to connect external equipment.
!
CAUTION
• Do not turn on the power to the CF-4700 FFT comparator with a USB flash memory connected.
Note that the CF-4700 FFT comparator, with a USB flash memory connected, cannot be started correctly even when the
power is turned on.
• The comparator does not work normally, either, when a USB device other than those recommended by Ono Sokki. For details
about the USB devices recommended by Ono Sokki, contact the distributor where you purchased the product or the nearest
Ono Sokki sales office.
(7)
SD CARD: SD card slot
Used to insert an SD card.
!
CAUTION
• Before using the SD card, be sure to format it with FAT32 or FAT (file system). Note that an unformatted SD card cannot be
used (not recognized).
• Always use an SD card recommended by Ono Sokki. Note that using an SD card other than recommended by Ono Sokki
could compromise the system performance or cause faults.
For details about the SD cards recommended by Ono Sokki, contact the nearest Ono Sokki sales officeor the distributor where
you purchased the product.
