If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.
The Tektronix 2247A is a 100 MHz four-channel analog oscilloscope, with a built-in 200 MHz counter/timer. (It is unknown if a 2247 non-A model was ever built.)
Channels 1-2 are fully-functioned, and 3-4 are very limited, in both deflection factor and coupling for digital signals.
|Deflection||CH 1&2: 2mV/div to 5V/div; CH 3&4: 0.1V/div and 0.5V/div all at +/- 2%|
|Vertical Operating Modes||CH1,2,3,4, CH2 Invert, Add, Alt, Chop (625 kHz)|
|Input Impedance||1M, 20pF|
|Sweep Speeds||A Time Base: 0.5s/div to 20ns/div; B Time Base: 5ms/div to 20ns/div (X10 Mag to 2ns/div)|
|Trigger||DC, Noise Reject, HF Reject, LF Reject, AC, TV Line, TV Field|
|Trigger Modes||A Mode: Auto Level, Auto, Norm, TV Line, TV Field, Single Seq. B Mode: Runs After Delay, Auto Level, Norm, TV Line (From A Source)|
