PDO-5000 series digital storage oscillograph
provides simple front panel with clear functions to
users for all basic operations. Scale and position of
various channels can provide intuitional operation
to meet usage habits of traditional instruments.
Users can use it skillfully without learning and
being familiar with operation for a long time. Users
can also press AUTO key directly to accelerate
adjustment and facilitate measurement.
Appropriate waveform and gear setup can be
shown on the instrument panel.
PDO-5000 series digital storage oscillograph
also has high-performance indicators and powerful
functions to fulfill measurement tasks quickly
besides easy usage. Quicker signals can be
observed by PDO-5000 series digital storage
oscillograph by real-time sampling of 500MS/s (or
1GS/s) and equivalent sampling of 25GS/s (or
50GS/s). It can capture and analyze waveform
easily by powerful trigger and analysis capacity.
Users can also observe and analyze signal
problems quickly and clearly by clear LCD display
and mathematical calculation function. We can see
that such ser
ies of digital storage oscillograph can
meet your measurement requirements by following
performance characteristics:
Double analog channels
High-resolution colorful LCD display system with
resolution of 320 240 or 800 480

PDO-5000 series digital storage oscillograph is
a small and handy desktop product. Basic test can be
done by providing convenient front panel to facilitate
operation for users.
PDO-5000 series are to provide simple front
panel with clear functions to users for basic
operation. Panel also includes knob and function key.
Knob functions are similar to those of other digital
storage oscillograph.
The chapter is to show execution of following steps
General inspection
5 keys in a row in the right side of display panel are
menu operation keys. (They are defined as F1 to F5
keys from top to b
ottom.) You can also set different
options for current menu by them. Other keys are
function keys. You can enter into different function
menus or gain specific function application directly
by them.

Elementary understanding of trigger system
Please know front operation panel firstly after
getting PDO-5000 series digital storage
oscillograph. The chapter is to introduce operation
and functions of front panel for
PDO-5000 products so as to be familiar with
usage within the shortest period.

General inspection
Function inspection
It is suggested to inspect the instrument by
following steps when getting a new PDO-5000
series digital storage oscillograph.
1. To check if there is damage due to transportation
or not.
Please replace carton or foaming plastic protection
cushion with severe damage instantly.
2. Please inspect fitting details and shown it in
“Fittings of PDO-5000 series digital Storage
Oscillograph” shown in the manual. You can check
if there are deficient fittings or not by referring to it.
Please contact HTC distributor or local agent if
there are deficient or damaged fittings.
3. Please ins
pect the entire machine and contact HTC
distributor or local agent for damaged appearance,
abnormal operation or failing to pass performance test.
Please pay attention to packages and report to
transportation department and HTC distributor if
machine damage is caused by transportation.
1. Connect the power supply
You can supply power to the machine and voltage is AC
100V to AC 240V. Frequency is 45Hz to 440Hz. It has
to press [UTILITY] menu and [F1] for self-correction
after power supply 30 minutes after operation of hot
machine so that digital storage oscillograph operates
under the
best status. As shown in Figure 1 4, please
enter into next page and press [F1] to call out ex-factory
setup.
－
HTC will arrange maintenance or replacement.
Please carry out once fast function inspection to
check if the machine operates normally or not.
Please operate according to following steps:

Warning: Please confirm safety grounding of digital
storage oscillograph to avoid dangers.
2. Signal access of digital storage oscillograph is
double-channel input for PDO-5000 series
digital storage oscillograph. There is also 1 EXT
TRIG INPUT channel. Please connect signals
according to following steps:
(As shown in Figure 1-5), connect probe of
digital storage oscillograph to CH1 input terminal
and set attenuation ratio switch on probe to 10×Á

button. As shown in Figure 1-7, square wave (1kHz,
about 3V and peak value) can be displayed within
several seconds. It has to inspect CH2 by the same
method then press [OFF] function button so as to
power off CH1. It has to press [CH2] function button
to power on CH2 and repeat the second and third
steps.

Probe compensation
It needs to adjust it when connecting probe to any
input channel for the first time so that probe can be
appropriate to input channel. Probe without
compensation correction can also bring in
measurement tolerance or error. Please operate
according to following steps for adjustment of
probe compensation:
1. To set probe menu attenuation coefficient to
10× and place probe switch to 10× then connect
digital storage oscillograph probe to CH1. Please
guarantee reliable contact to probe. It has to
connect probe end to signal output connector
2
of
probe compensator then connect grounding clip to
earth wire connector of probe compensator. It also
has to power on CH1 and press [AUTO].
3. Adjust variable capacitance on the probe by
screwdriver of non-metallic handle for waveform
display of “insufficient compensation” or
“excessive compensation” shown in above figure
until “correct compensation” for waveform display
on the screen as above.
Warning: Please guarantee perfect insulation
conduits of probe and do not contact metallic part
of probe when connecting to HV source to avoid
electric shock of probe during HV measurement.
