TIME BASE
Crystal Frequency: 10 MHz
Stability:
Aging Rate: <3 parts in lOVmo.
Temperature: <±2.5 parts in I0 fi , 0° to 50°C.
Line Voltage: <±1 part in 10 T for 10% line
variation.
Short-term Fluctuation: Typically <5 parts
in 10 9 , one-second average (at con¬
stant temperature)
Oscillator Output:
10 MHz, TTL type output levels, 50Q series
impedance at rear panel BNC
External Input: 100 Hz -10 MHz; 1 V rms into IkO
Time Base Output:
Negative pulses, ±3 V to 0 V (open circuit),
typically 100 ns wide. In START, output is
10 MHz divided by TIME BASE/MULTIPLIER
switch setting. Available at rear panel BNC.
Gate Output:
TTL level pulses; low while gate open, high
while gate closed. Available at rear panel
BNC.
GENERAL

Blanking:
Suppresses display of unwanted zeros left of the
most significant digit
Display Storage:
Holds reading between samples. Rear panel
switch overrides storage
