This is a Heathkit Model IO-104 15 MHz Triggered Sweep Oscilloscope that I built around 1974. I purchased this scope primarily to troubleshoot a digital clock that I designed and built. Once I got the clock running, I used this scope to look at radio signals on my Heathkit GR-54 shortwave receiver. Now, I use the scope to display the output of the spectrum analyzer I built. You can see the spectrum analyzer by clicking HERE.
Below are some specifications for this scope:
Vertical Amplifier:
0.1V/CM - 50 V/cm +/- 3%; 12 positions
Sensitivity: 10mv/cm
Bandwidth: DC - 15 MHz +/- 3 dB with 4 cm deflection
Rise Time: 24 ns
Input Impedance: 1 M shunted by 40pF
Input Coupling: AC, GND, DC
Time Base:
Sweep Speed: 2 s/cm to 0.2 us/cm, +/- 5 %; 22 steps
Horiz. Expansion: x5 +/- 5 %x
Dual Trace Display:
Mode: Ch1, Ch2, X-Y, Dual, Add, Differential
Triggering: Normal/Auto, +/-, Internal, External, AC/DC
Horizontal:
Input Impedance: 1 M
Sensitivity: <0.5V/cm
Freq. Response: DC to 1 MHz, +/- 3 dB
Anntenuator: 2 position, X! and X10
I have used this scope for may projects over the years and it still works fine.
