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

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.
