ACCESSORIES
Test Accessories
Type 107 Square-Wave Generator
Risetime
Less than 3 millimicroseconds into a terminated 52-ohm
cable.
Frequency Range
Approximately 400 kc to 1 me, uncalibrated.
Output Voltage
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 53/54K 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 53 /54 Wide-Band
Preamplifiers.
Waveform— Special design consideration has been
placed on the shape of the positive portion of the wave
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
400 kc to 1 me.
Output Voltage— 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.
Output Trigger— An output trigger signal is available
at a coaxial connector at the rear of the instrument.
M E C H A N I C A L SPECIFICATIONS
