Type 107 S q u a re -W a v e G en erato r
Risetime
Less than 3 millimicroseconds into a terminated 52-ohm
cable.

Approximately 400 kc to 1 me, uncalibrated.
Output V o ltag e
0.1 to 0.5 v, approximately, when cable is terminated
in 52 ohms.
GENERAL
D E S C R I P T I O N
The Tektronix Type 107 Square-Wave Generator is
basically intended as a Test Accessory for the Type 540-
Series Oscilloscopes. For examination of high-frequency
response, a square wave having a risetime faster than
that of the amplifier being tested is necessary. The Type
540-Series Oscilloscopes with the Type 5 3 /5 4 K Plug-In
Preamplifier have a combination risetime of 1 2 millimicro­
seconds. The Type 107, with its risetime of 3 millimicro­
seconds, provides a suitable square wave for checking
and adjusting the high-frequency response of the Type
540-Series Oscilloscopes and Type 5 3 /5 4 W ide-Band
Preamplifiers.
W a v e fo rm
— Special design consideration has been
placed on the shape of the positive portion of the w ave­
form. Therefore, only this portion should be used in tran­
sient response testing.

CHARACTERISTICS
Risetime — Less than 3 millimicroseconds when the
output 52-ohm cable is terminated.
Frequency Range
— A front-panel control varies the
frequency over an uncalibrated range of approximately
40 0 kc to 1 me.
O utput V o lta g e — When the output cable is termin­
ated the output voltage range is approximately
0 . 1
v to
0.5 v. If the cable is not terminated, the voltage range is
0 . 2
v to
1
v.
O utput Trigger — An output trigger signal is available
at a coaxial connector at the rear of the instrument.
