(1) Frequency: 50 (internal), 100, 150, 200, 400 Hz
(2) Rotation: in steps of 30°, rotatable 360°
(3) Operating modes: ellipse — expanded — straight line
(4) The high-frequency time base ellipse can be adjusted to normal size according to the input voltage (10-250V), with a power consumption of <1 VA and automatic overload protection
Display unit
Uses a 124×104mm² rectangular oscilloscope tube, with brightness and focus adjustment knobs
Amplifier
(1) 3dB low-frequency cutoff fL: 10, 20, 40 kHz selectable
(2) 3dB high-frequency cutoff fH: 80, 200, 300 kHz selectable
(3) Gain adjustment: coarse adjustment in 6 steps, with a gain difference of 20±1 dB between steps, fine adjustment range >20 dB
(4) Asymmetry of positive and negative pulse response <1 dB
Time window
(1) Window width: adjustable, 15° to 150° at 50 Hz
(2) Window position: each window can be rotated 0° to 170°
(3) The two time windows can be opened separately or simultaneously
Pulse peak meter
(1) Linear scale pointer meter 0-100, error ±5% (based on full scale)
(2) Logarithmic scale pointer meter 0-10-100, error ±5% (based on full scale)
(3) Digital meter: 3½-digit LED digital display 0-100, error: ±3% (based on full scale)
Test voltage meter
(1) Range 100kV (using 100kV voltmeter resistor R)
(2) Display: 3½-digit digital voltmeter
(3) Error: ±3%
Zero marking system
(1) The zero mark of the internal zero generator can change polarity and can be rotated 0-180° to match the polarity of the true zero mark produced by the voltage resistor R
(2) The zero mark is synchronized with all elliptical scanning frequencies
