Other Functions
External Signal Input/Output
In addition to input terminals for measurement, input/output terminals for exchanging
signals with external devices are provided on the front and rear panels. For the locations
of the terminals, see section 1.1, “Front Panel and Rear Panel.”
10-MHz Reference Input (see section 6.8 on how to use it)
The TA720 generates a reference clock signal internally for making measurement, but
an external signal applied to the 10MHz REF IN terminal on the rear panel can be used
in place of the internal clock signal.
10-MHz Output (see section 13.3 on how to use it)
The internal reference clock signal or the externally applied reference clock signal is passed
through a 10-MHz band-pass filter and is continuously output from the 10MHz OUT terminal.
Monitor Output (see section 13.5 on how to use it)
The signal applied to the input terminal is voltage divided to approximately half its value
and output from this terminal.
This signal can be used to check the waveform when phase correcting a probe. Which
channel’s input signal is output varies depending on the measurement function.
External Arming Input/External Gate Input/Inhibit Input
These signal inputs are used to externally control the measurement functions of the
instrument. The external arming input terminal is shared with the external gate input
terminal. For the functionality of the external arming and inhibit input signals, see section
2.5, “Setting Measurement Conditions.”
Storing and Recalling Setup Data (see chapter 10 for the operating procedure)
Up to 32 sets of setup data can be stored in the internal non-volatile memory. The
stored setup data can also be recalled to set up the instrument. This function is useful
when the same setup is used often.
Saving and Recalling Data to/from the Floppy Disk or PC Card (see chapter 11 for the
operating procedure)
The TA720 comes with a floppy disk drive as standard. A PC card slot is also provided
as an option.
The setup data and measured data can be saved to the floppy disk or PC card and
recalled when necessary. An image of the screen can also be saved in TIFF, BMP, or
PostScript format. You can create reports by pasting the screen image data to a
document created using a word processor.
Communications (see chapter 12 and the Communication Interface User’s Manual for
the operating procedure)
The Ethernet interface (optional) or the GP-IB interface can be used to perform communications
with other devices such as a PC. Data can be saved on a network drive via the Ethernet
interface or the floppy disk or PC card of the TA720 can be accessed from a PC. In addition, the
measured data can be output to a PC via the Ethernet interface or GP-IB interface to be
analyzed or the TA720 can be externally controlled using communications.
