Information

High Sensitivity Sensitivity as high as 1 mV/div. Wide Bands The frequency band is DC to 5 MHz (- 3 dB) at 1, 2 mV/div and DC to 20 MHz I DC to 40 MHz for CS-4035 1 (— 3 dB) from 5 mV/div. Continuous Switching Attenuator A rotary switch enables vertical axis sensitivity to be adjusted continuously from 1m V/div to 5 V/div. High Speed Sweep High speed sweeping is possible at a time base of 50 ns/div Iduring x 10 MAG) I 20 ns/div for CS-4035 and CS-4026 |. High Accuracy Accuracy within 3% for both vertical axis sensitivity and sweep time. Large Aperture The 150 mm rectangular CRT monitor features an internal graticule easy visual recognition of waveforms. The waveforms displayed in high brightness can be monitored with no parallax. Acceleration voltage: 12 kV for CS-4035 and CS-4026 2 kV for CS-4025 Trace Rotation The horizontal trace angle is easily corrected. Automatic Free Run The trace can be checked even when there are no trigger signals to be input, revision Trigger With a specially designed circuit, adjustment-free, stable synchronization for both frames and lines can be realized over the whole range from large to small amplitudes. One Touch X-Y Switching to X-Y operation at the touch of a lever switch. Automatic Trigger Signal Selection Trigger signals can be selected automatically according to the VERT MODE control setting by simply switching the SOURCE control to VERT. CH1 OUTPUT A channel 1 output terminal has been added for CH1 input signal monitoring. High Stability, High Reliability Hybrid integrated circuits have been employed in all the components, realizing high standards in terms of both stability and reliability. Prevention of Trace Line Jump When Selecting Input Signal Coupling Better operability has been achieved with an anti- trace line jump circuit that prevents sudden changes in the trace position when input signal coupling is switched from GND to AC position. Scale Illumination The scale illumination function makes it possible to take photographs of waveform data displayed on the CRT in a darkend room. | CS-4025 does not have this function )
