USER MANUAL

This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, cable of
0.75mm2should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection method
used.
Any moulded mains connector that requires removal /replacement must
be destroyed by removal of any fuse & fuse carrier and disposed of
immediately, as a plug with bared wires is hazardous if a engaged in live
socket. Any re-wiring must be carried out in accordance with the
information detailedonthis labelandlocalregulations.

1. PRODUCT INTRODUCTION
1-1. Description
The ISR-6051 oscilloscope is a 50 MHz, two-channel, portable
oscilloscopes for general purpose use. A microprocessor-based operating
system controls most of the functions of the instrument, including cursor
readout and digitized panel setting. On-screen alphanumeric readout and
cursor functions for voltage, time and frequency measurement provide
operational convenience. It also has the function of auto measurement for
frequency and counter. Ten different user defined instrument settings can be
saved and recalled.
The vertical deflection system has two input channels. Each channel has 14
basic deflection settings from 1mV to 20V per division. The horizontal
deflection system provides sweep times from 0.5s to 0.2μs per division.
The trigger system provides stable triggering over the full bandwidth of the
vertical deflection system.

1-2. Features
The oscilloscope offers several additional features:
1) High intensity and internal graticule CRT;
The oscilloscope employs a high intensity 6-inch rectangular screen
cathode-ray tube with red internal graticule. It displays clear readable
traces even at high sweep speeds. Internal graticule lines eliminate
parallax-viewing error between the trace and the graticule line.
2) Frequency counter:
An in-built 6-digit frequency counter is accurate to ±0.01% when
measuring frequencies between 1kHz to 50MHz and ±0.05% when
measuring 50Hz to 1kHz.
3) ALT-MAG function:
The primary sweep waveform together with the magnified sweep
waveform can be displayed simultaneously using the ALT-MAG
function. The magnification ratio can be selected from three levels of ×
5, ×10 or ×20 to allow detailed inspection of the displayed waveform in
the centre of the CRT.
4) Convenient VERT-MODE triggering:
The sync signal source is determined automatically when the vertical
axis mode is changed, thereby removing the need to change the trigger
source every time the VERT-MODE is changed.
5) TV triggering:
A TV sync-separator circuit permits stable TV signal measurements on
field, frame and line signals.
6) Hold-off:
The function allows the stable synchronization of complex waveforms
that are difficult to synchronize by adjusting the trigger level alone.

7) CH1 Signal output:
The CH1 signal output is obtained by splitting the input signal in the
middle of the signal line. As the connector provides the input signal at a
level of 50mV/div, connecting a frequency counter makes it possible to
measure the frequency of a very low-level signal while observing its
waveform.
8) Z-axis intensity modulation:
For applying a blanking signal from an external source. The trace
displayed on the screen may be intensity-modulated where pulse signal
or time-scale marks are required.
9) LED indicator and buzzer alarm:
The LED’s located in the front panel assist operation and indicate
additional information. Incorrect operation and the electrical
end-of-travel of control knobs are indicated by a warning beep.
10) SMD manufacturing technology:
The instrument is built using advanced SMD technology to reduce the
amount of internal wiring and shorten the foil route on the printed
circuit boards. This increases the high frequency performance and the
reliability of the product.
11) Compact size (275W×130H×370D)mm and logically grouped front panel
controls provide ease of use.
