Features

●Programmable function
Internal non volatile program memory allows programmed sequences of up to 100 steps.
Optional RS-232C or GP-IB interface card enable bus controlled set up and waveform adjustment.

●Parameter Auto Measurement Function
It is possible to measure the voltage, frequency and period automatically just input the signal. Especially for voltage measurement, measurement mode is automatically selected according to the input selector. For example, when the AC input is selected, "Peak-to-Peak" voltage is automatically measured, and when the DC input is selected, DC voltage is measured automatically.

●Auto Setup Function
By pressing the AUTO SET key, the voltage range and time range are selected automatically.

●Cursor Measurement Function
The cursor measurement function allows a high accuracy measurement of signal values. When the probes are used, its attenuation ratio can be converted automatically. It is also possible to measure the voltage value and phase differences. When the delay sweep is used, the delay time is also displayed, enabling an accurate measurement results without any errors due to visual checks in conventional systems.

●High-Sensitivity Design with Vertical Axis of 1 mV/div
The vertical axis sensitivity can be varied continuously from 1 mV/div. to 5 V/div. using the 1-2-5 step attenuator. The 1 mV/div. position is very useful to measure low-level and complicated signals. (Frequency response at 1 mV/div. and 2mV/div are DC to 20 MHz (-3 dB)).

●Automaticv Sync (FIX) Function
With this function, the synchronization level is automatically controlled by tracking the amplitude of the waveform to maintain the sync lock status. This function eliminates annoying and complicated synchronization operations.

●Easy Operation Panel Layout
The CS-5370P used touch switches and LEDs.

●Delayed sweep with waveform partial magnification capability
The main (A) sweep waveform in which the magnified section is brightened by intensity modulation and the delayed (B) sweep waveform which shows only the magnified section can be observed simultaneously. This is a real alternate delayed sweep.

●High-Accuracy ± 2% Design for More Precision Measurement
In order to obtain highly reliable measurement results, the vertical axis sensitivity and sweep time for the main circuit is maintained within ± 2% precision. Other specifications also guarantees the rated values (under temperature conditions of 10 to 30°C, humidity of 85% or less).

●Square-Type 150 mm CRT with Self-Illuminated Light and Inside Scale (17kV)
A large-sized, square, dome-mesh type CRT with rear accelerator is employed. It features both high intensity and high resolution while providing accurate measurements without parallax view. The auto focus circuit is also incorporated to display sharp waveforms at all times.

●Single sweep for observations of single-shot channel
The single sweep function is powerful in measurement of single-shot or sudden channel. Waveform photography using a camera is as easy as ordinary, visual observations. It is easy not only for observations during normal visual inspections but also for camera shots of the waveforms.

●Variable hold-off allowing observation of waveforms with complicated cycle
Signals which are hard to be synchronized due to complicated repetition cycles, for example digital signals and video signal bursts, can be synchronized stably by converting them into the hold-off time.

●High-Accuracy Calibration Signals
A calibration signal output is provided to output the highly accurate frequency of ± 0.1% and voltage accuracy of ± 1%, enabling checking of the measurement precision at any required time.

●CH1 signal output connector
The CH1 signal output is obtained by branching the input signal in the middle of the signal line. As this connector outputs the input signal at a rate of 50 mV/div, connecting a frequency counter makes it possible to measure the frequency of a very low signal while observing its waveform

●Wide Dynamic Range and Distortion-Free Accurate Waveform Display
Its wide dynamic range having greater margins assures the linearity of the waveforms displayed on the CRT, providing highly accurate waveform displays without any distortion up to the upper frequency limits.
