Horizontal (X-Axis)
-3dB Bandwidth
3 MHz or more.
Phase Match (DC Coupled) ±3 degrees from do to 50 kHz.
EXTERNAL Z-AXIS INPUT
Active Region Lower
Threshold (intensity
decreases above this
voltage)
+1.8 volts or less.
Signal Required to
Modulate an A or B Trace
+3.8 volts or less provides noticeable modu
lation of a normal intensity trace.
Usable frequency range is dc to 10 MHz.
External Z-Axis signal does not affect the
readout or the intensified zone intensity.
Maximum Input Voltage A 30 V (dc + peak ac); 30 V p-p ac at 1 kHz
or less.3
Input Loading
Represents less than one LSTTL load.3
