Main Features

High intensity
The CRT incorporates high beam transmission,
and
high intensity, and a 2kV high acceleration voltage.
The CRT displays clearly readable traces even at
acceleration
higher sweep speeds.
CRT
Wide
In addition to the DC‐30MHz (‐3dB) wide
bandwidth and
bandwidth, the oscilloscope provides a 1mV/DIV
high sensitivity. The 30MHz frequency range is
sensitivity
obtained by an improved triggering
synchronization.
Frequency
A built‐in 5‐digit frequency counter offers ±0.02%
Counter
accuracy between 1kHz and 30MHz, and ±0.05%
between 50Hz and 1kHz.
Automatic
Pressing the AUTO TIMEBASE key automatically
timebase
adjusts the sweep time to an appropriate range.
adjustment
Alternate
Even when observing two waveforms in different
triggering
frequencies, both waveforms can be stably
triggered using the alternate triggering mode.
TV sync
The oscilloscope has a sync separator circuit for
triggering:
the TV‐V and TV‐H signal triggering.
CH1 output
The CH1 signal is output from a rear panel
terminal, which can be applied to external devices.
Z-axis input
Display intensity can be controlled via the TTL
compatible z‐axis input on the rear panel.
X-Y mode
The X‐Y mode compares the CH1 and CH2 signal
amplitude. It is useful for comparing the phase
difference.
Buzzer alarm
Incorrect operation generates a warning beep.
