1.7 Other Functions
External Signal Input/Output (Rear Panel)
≡
For operating procedure, refer to 10.2 and 10.3
≡
The following input and output terminals (BNC) are provided on the rear panel, to communicate
with external devices. For location of each terminal, refer to 2.2, “Rear Panel”.
Reference input terminal (REFERENCE IN)
Although the instrument has an internal reference clock to be used for measurements, it is
possible to input an external signal (10 MHz) to this terminal and use it as the reference clock.
Reference output terminal (REFERENCE OUT)
The internal reference clock or external reference clock can be sent through a 10-MHz band pass
filter and then output from this terminal.
Monitor output terminals (MONITOR OUT CHA, CHB)
Signals input to the input terminals can be output directly from these terminals. They can be used
for observation of a waveform during phase correction of a probe.
External arming input/inhibit input terminals (EXT ARM IN, INHIBIT IN)
These signals are used to control measurement functions of the instrument. For the function of
external arming or inhibit signal, refer to 1.5, “Setting the Acquisition Conditions for Input Signal
to be Measured”.
Communications
≡
Refer to the GP-IB Interface User’s Manual (IM704210-12E)
≡
The instrument is equipped with a GP-IB interface as a standard feature. Use of this interface
enables transmission of measured data to a personal computer to analyze it, and enables control of
this instrument using an external controller.
Storing and Recalling of Set-up Information
≡
For operating procedure, refer to Chapter 8
≡
Up to 10 sets of set-up information can be stored in the internal non-volatile memory. It is also
possible to recall the stored set-up information to set up the instrument. This function is useful
when you want to use the set-up information repeatedly.
Saving and Loading Data from a Floppy Disk
≡
For operating procedure, refer to Chapter 9
≡
The instrument is equipped with a floppy disk drive. This enables the user to save set-up
information and measured data to a floppy disk or load from it, whenever it is required. In
addition, it is also possible to save the screen image data in TIFF format. This enables the user to
import the saved screen image data to a document created by a DTP software application, to
create a report.
Auto Loading of Set-up Information
≡
For operating procedure, refer to 9.3
≡
Turning ON the power after a floppy disk containing the set-up information is inserted into the
floppy disk drive will load the set-up information to the instrument automatically. This is useful
to restore the set-up information in the instrument.
Plotter Output
≡
For operating procedure, refer to 10.1
≡
Measured data can be output to an external plotter via the GP-IB interface.
Initialization of Set-up Information
≡
For operating procedure, refer to 10.4
≡
The set-up information can be reset to the factory settings (default settings).
Calibration
≡
For operating procedure, refer to 10.5
≡
Calibration of the offset voltage of each input amplifier and conversion factor of each T/V
converter can be carried out using the internal calibration signal.
