No... There are optional Tools besides the Clip-On KV Coil and Ignition Pick Up. The others would included an Inductive Chrome Clamp that grabs any of the Ignition Wires leading to the Spark Plugs (Mostly used to confirm Actions on the #1 Cylinder where a Secondary Coil is Firing Very High KV and thus... having an intermediate 10:1 or even Hantek 20:1 High Voltage Attenuation in between will protect the KV Unit and the Base Unit.
You can also use a Flat Pick Up Unit that can lay over the tops COP (Coil Over Plugs) and grab the Ignition Wave Forms thusly. The others would be the Low and High Amperage Clamps like the Hantek Models CC-65 Low Amp Clamp and the Hantek Model CC-650 High Amp Clamp.
They work by passively sensing the Internal Voltages via the Magnetic Fields they create. Then they convert them into Milli-Volts such as: 1 Amp = 1 Milli-Volt and then display them as Voltage Over Time on the Adjusted Screen.
Amp Clamps do not require the use of any Attenuators.
The Scalers involved here are the variable Ranges of Voltages and the Time Bases chosen for their capture and display.
THAT is where the
"Secret Sauce" of having a decent skill set comes in handy when setting up What appears Where on the X and Y Axis.
Remember that the ONLY thing that any Oscilloscope does is display Voltage Over Time on an X/Y Scale on Screen. The early model Vantage Diagnostic Tools do have a relatively Low Sample Rate when compared to say... The Vantage Pro, The Autel Model# MP408... or "The King Of Automotive Scopes"
...like my MICSIG... But they can admirably perform Basic Oscilloscope Diagnostics. Observe James Danner at work using his
Solus Scan Tool along with the Scope Features of
BOTH his
Vantage ...
AND... his
Vantage Pro Diagnostic "O" Scope Features
(Yup... He is Paul "Scanner" Danner's Brother):
