Tektronix ‘IDS 340, TDS 360, and ‘IDS 380 oscilloscopes arc digital signal
processors and are superb tools for displaying and measuring waveforms. Their
performance addresses the needs of both benchtop lab and portable applications

with the following features:

Two input

Chdnneb,

each with a record length of 1,000 samples and X-bit

vertical resolution. Both channelS acquire waveforms simultaneously.
2 Gigasample/sccond maximum sample rate (TDS 380); 1 Gigasamples/

second maximum sample rate (TDS 360); 500 McgasamplesIsecond
max,imum sample rate (TDS 340).

400 MHz analog bandwidth and fastest time base setting of 2.5 nsidiv
(‘IDS 380): 200 MHz analog bandwidth and fastest time base setting of

2.5 ns/div (‘IDS 360); 100 MHz analog bandwidth and fastest time base
setting of5 ns/div (TDS 340).

A full complement of advanced functions including on-screen readout,
AUTOSET, cursors, continuously updated automatic measurements, and
FFT.

Waveform averaging, waveform enveloping, and hardware peak. detection.
Floppy disk drive (TDS 380 and TDS 360) for mass storage of waveforms,

setups, and hard copies.
A unique graphical user interface (GUI) and a logical front-panel layout

which combine to deliver the standard in usability pioneered by the TDS
family of oscilloscopes.

To properly install and power on the oscilloscope, perform this procedure.

Check that you have the proper elccttical connections. The rear label lists

1.
power requirements for all possible voltage’inputs.

2.

Check the fuse to bc sure it is the proper type and rating (Figure l-2).
TDS 300 Series oscillo~copcs are shipped with a UL-approved fuse installed.

Fuse specifications are as follows:
S mm x 20 mm, time-lag, 3.15 A, 250 V. or

1.25 in x 0.25 in, cimc-lag, 3 A, 250 V

3.

Connect the proper power cord from the rear-panel power connector

(Figure l-2) to the power system. Use the power cord clamp to secure the

cord to the rear panel.

4.

Leave space for conlmg. Do this by verifying that UK air-intaks and exhaust

holes on the sides and bottom of the cabinet (where tttc fan operates) are free

of any airflow obstructions.

The TDS 340, TIX 360, and TDS 380 come wilh two standard-accessory
probes. Use these probes to conduct signals to the oscilloscope. For detailed
probe specifications and instructions, see the instruction manual packaged with
the probe.

Connecting a Probe

To connect a probe to the oscilloscope, attach the BNC end of the pro:bc to &her
the CH 1 or CA 2 inpul. Be sure to twist the probe end clockwise until tie BNC
is fully locked. See Figure 2-3.

Compensating a Probe

Use the following procedure to compensate the probe every tim,c you set up your
oscilloscope.

ppendix B: Performance Verification

The procedure in this appendix verities that the ‘HIS 340, TDS 360, and
TDS 380 oscilloscopes meet warranted specifications. Dcpcnding on what you
want to accomplish, you may prefer to perform another procedure you can find
elsewhere in this manual.

To rapidly conCm th;lt this oscilloscope functions, just do the procedures
under Se~~.~ts, which begin on page l-5.

Advantages: This procedure is quick to do, requires no external equipment
or signal sources, and performs extensive functional and accuracy resting to
provide high confidence that the oscilloscope performs propefl,y. You can use
it as a quick check before making a series of important measurements.

Conventions

To further check function&y, do the procedures under

Functional Tests

begin on page l-7.
Advantages: Thcsc procedures require minimal additional time to perform,

require no additional equipment other than a

StandaId-aCCCSSOry

probe, and

more completely test the internal hardware of this oscilloscope. You can use

them to quickly determine if the oscilloscope is suitable for pulting into

service, such as when it is first received,

Prerequisites

The tests in this subsection comprise an extensive, valid confrrnation of
performance and functionality when the following requirements are met:

The cabinet must bc installed.
You must have performed and passed the procedures under Self Tests, on

page l-5 and those under Functional Tests, on page 1-7.
The digitizing oscilloscope must have been operating for a warm-up period

of at least 20 minutes, and must bc operating at an ambient tcrnperature
between -10” C and +5S” C.
