Chapter 2 Getting to know your oscilloscope communication and

control software

2.1 The control panel

After the oscilloscope communication and control software is activated, a display panel similar to the
digital storage oscilloscope operation interface will pop up. This is the virtual oscilloscope control panel.
When transmitting data, you can observe the current waveform displayed by the oscilloscope on the
virtual control panel. This interface also features menus, controls and knobs for accessing waveform and
channel parameters (please disable the “data transmission” function before using the menus to access
information). Please see below for detailed operation instructions.

2.2 Main menu

Fig 2-1 shows four menus under the main menu on the top left corner: document, function, waveform
refresh and help. Their operation instructions are as follows:

1. Document

Load : This means saving the oscilloscope communication and control software to the

computer hard disk or other storage media.

Save : This means saving the waveform currently on the virtual display panel to a computer or

other storage equipment. Select “Document” → “Save” and save it on the hard disk or
mobile external hard disk in *.dat format. Assign any file name you like.

Record : Enable the “data transmission” function and select “Document” → “Record”. A prompt

box shown in Fig 2-2 will pop up on the virtual display panel and recording of the
virtual display waveform begins. The recording prompt box shows the current
waveform recording progress. To pause recording, simply click the “pause” button. To
resume, click the “continue” button and recording will resume from the point where it
was paused.

The dialog box in Fig 2-3 appears when you close the waveform recording function or
recording has reached the maximum number of data screens. Click “YES” in Fig 2-3 to
save it in *.rec format on the computer hard disk or other storage device. If you wish to
abandon recording, press “NO” as shown in Fig 2-3. The waveform record ing function
can record up to 1000 screens of data.

6. On the virtual control panel in Fig 3-4, you can operate your oscilloscope with different buttons as
instructed by the oscilloscope

operating manual.

7. When operation is complete press [QUIT] to close this screen.

Note : The “data transmission”, and “Far control” functions cannot be operated simultaneously.

3.2 Ethernet (LAN) interface controls

The Ethernet port is a dedicated interface module of UT

D4000 Series Digital Storage Oscilloscopes. This

TCP/IP protocol embedded module can provide direct Ethernet connection to a UT

D4000 series
oscilloscope. After installing the communication and control software, you can operate your oscilloscope
on remote control through LAN or the Internet. As it supports concurrent visit by multiple users, there are
no geographical and users restraints and you can carry out network and remote testing as well as
measuring.

With the optional UT-M06 Ethernet module, you can operate the oscilloscope through the LAN interface
as follows :

1. Select “LAN” in the equipment selection option on the real-time control panel.

2. When “LAN” is selected, the dialog box in Fig 3-5 will pop up.

Fig 3-5

Enter the DSO IP address in this box. The IP addresses set in the software and the communicated
oscilloscope must be the same, otherwise communication between the oscilloscope and the software
cannot be established.

Please refer to the oscilloscope

operating manual for operation instructions. Access sub-menu page 2 by
pressing [UTILITY] → LAN on the oscilloscope control panel for TCP/IP protocol setup. You should set
up the IP address, netmask and default gateway in LAN. In the same network, the IP address of every
individual digital storage oscilloscope is unique and must not conflict with th e IP address of any other
equipment (in-network IP addresses).

3. For other operation instructions refer to steps 2, 3, 4, 5, 6 and 7 for “USB interface controls” in this

chapter.

Note : When using the LAN interface, you can operate the oscilloscope by remote control via LAN or
the Internet. Mapping feature of the router must be enabled and the public network address of your
company should provided.

3.3 GPIB interface controls

The GPIB port is a dedicated interface module of UTD4000 Series Digital Storage Oscilloscopes. After
installing the communication and control software, you can carry out system operation and control your
oscilloscope through the GPIB interface. You can create an automatic testing system simply, quickly and
efficiently, and carry out testing and measuring.

With the optional UT-M06 extension module, you can operate your UT

D4000 oscilloscope through the

GPIB interface as follows :

1. Select “GPIB” in the equipment selection option on the real-time control panel.

2. When “GPIB” is selected, the dialog box in Fig 3-6 will pop up.

Fig 3-6

Enter the GPIB device address in this box (range : 1-30). The GPIB device addresses set in the software
and the communicated oscilloscope must be the same, otherwise communication between the
oscilloscope and the software cannot be established.

Access sub-menu page 2 by pressing [UTILITY] → GPIB on the oscilloscope control panel for GPIB
device address setup.

There must not be two identical GPIB device addresses on one GPIB main line.

3. For other operation instructions refer to steps 2 and 3 for “USB interface controls” in this chapter.

Note : When using the GPIB interface, the “transmission interface” feature is disabled.
