Other Functions
Communications (GP-IB) «See chapter 8 for the operating procedure»
The GP-IB Interface comes standard with the TA120E. You can output the jitter or jitter
ratio of the selected measurement function to a PC or control the TA120E from an
external controller.
Storing and Recalling Setup Information «See chapter 6 for the operating procedure»
Up to seven sets of setup information can be stored in the internal non-volatile memory.
You can also recall the stored setup information and change the settings.
Backing Up Setup Information «See 7.3 for the operating procedure»
The setup information is stored using a lithium battery. When the power switch is turned
ON, the TA120E starts the measurement using the settings that existed immediately
before the power switch was turned OFF. If the setup information can no longer be
stored due to a dead lithium battery, the TA120E is reset to the factory default settings.
Initializing Setup Information «See 7.4 for the operating procedure»
The TA120E has the following two methods of initializing the setup information.
• Initialization to factory default settings
• Initialization of the information excluding the following settings:
Communication address
Stored information in the internal memory
Version Display «See 7.5 for the operating procedure»
The firmware version (ROM version) of the TA120E can be displayed.
Key Lock «See 7.6 for the operating procedure»
You can disable the front panel key operation.
Adjusting the Zero Position of the Needle «See 9.3 for the operating procedure»
You can adjust the zero position of the needle.
Self-Test «See 9.4 for the operating procedure»
If you are in doubt as to whether the instrument has malfunctioned, you can run a self-
test before contacting a YOKOGAWA dealer. You can check things such as the keys,
rotary knob, indicator, meter, and board.
Calibration «See 9.5 for the operating procedure»
Using the internal calibration signal, the offset voltage of the input amplifier and the
conversion coefficient of the time-voltage converter can be calibrated.
Detection of a Cooling Fan Malfunction
The condition of the cooling fan is monitored at all times. If the fan stops, error code 906
is shown on the display. In this case, immediately turn OFF the power. If you continue
to use the instrument, a warning is given approximately every 10 s by displaying the
error code until the cooling fan recovers.
