Information:

The LBO-588CI is a Dual trace, delayed-sweep, programmable Oscilloscope that allows all scope mode settings. This includes variable controls which are easily stored in a 100-address internal memory and can be recalled whenever needed. It features 5 mV/div (30 MHz) and 1 mV/div (20 MHz: MAG X 5), and a maximum sweep rate of 20 ns/div (MAG X 10), with a 6-inch rectangular metal-back CRT with a high-brightness, internal graticule. T le waveform clamping function of the LBO-5880 and its ability to set two marker cursors for waveform amplitude adjustment provide an ideal measuring instrument for use in the production and servicing of TV sets and VTRs. 2. FEATURES 1 Oscilloscope Section The 6-inch rectangular CRT with an internal graticule, supported by regulated high-acceleration voltage power supplies, yields accurate, error-free measurement reading. The aluminized CRT also offers added intensity, assuring adequate brightness for delayed sweeps. Scale illumination and beam rotation functions are also provided. A single-key selection of high-sensitive 1 mV/div (20 MHz) facilitates the measurement of ripples in regulated power supplies and weak signals in biological and Other research activities. The delayed sweep function, independent A and B trigger selection function, and separate external trigger input connectors support a wide range of observations. The maximum sweep rate can be quickly magnified to 20 ns/div by the 10 (times) magnifier, thus enabling the display of 30 MHz waveforms in six sweep periods on the screen. The ALT trigger function yields static waveforms of two types of signals with different timing relations. A built-in synchronous sampling circuit eases synchronization with TV composite video signals. Since the vertical (VIDEO-V) and horizontal (VIDEO-H) sweep periods are selectable regardless of the TIME/DIV switch setting, the waveform in the horizontal sweep period can be synchronized and observed with the vertical sweep period. Variable hold-off time enables video signals and pulse strings from computers (such as digital word pulses) to be observed in stabilized periods. The B ENDS A function lessens flickering during magnified delayed sweeps. ADD and CH 2 polarity selections make it possible to observe the sum of difference between two signals and to also display an accurate picture of push-pull signals. Signals applied to CH 1 can be isolated from the vertical preamp via a buffer. Since this output is about 0.1 V p-p per division on the screen, the LBO-5880 can be used as a super-high sensitive Counter when this output is connected to a Counter. The LBO-5880 can be switched by a one-key operation to an X-Y Oscilloscope having CH 1 as the X-axis and CH 2 as the Y-axis. Extensive use of custom ICs establishes enhanced reliability. The GND TEST switch allows checking the GND level at a single touch, independently of the program. Each function mode of the Oscilloscope is constantly displayed on a panel LED. This LED display can be suppressed by a switch.
