Modules Support

Automotive Module: supported up to 2KSa/s (for 2 Channels)
Audio Module: NOT supported

Advantages

High ADC resolution
Wide input range

Disadvantages

Low sampling rate
Low real-time acquisition rate (for Automotive Module) up to 2KSa/s with 2 Channels

Additional notes

The 4 channels work from version 2.3.2 with a recent HScope license. In case you have a license older than 1 year (before Jan 2020) the 4 channels will be available just with the Update 2020 license or if you buy any other new license.

The trigger works just on Channel 1 and Channel 2.

The maximum rate and number of samples is split among the enabled channels. Once you set 2 or 4 channels enabled the list of rates get updated with the available values.

Specific Configurations

This device has specific configurations in HScope. It is possible to change Channel 3 and Channel 4 to be any other between Channel 3 and Channel 8. You can find these configurations under Settings -> General -> Hardware.

Note: this setting is allowed just if Channel 4 is set to another channel greater than Channel 3. For example you can set Channel 4 to be Channel 8 and then set Channel 3 to be Channel 6.

Input Voltage Range

The range ±20V is linear and the only suggested to use. In this range the oscilloscope has a noise around 40-60 mVpp.
In case it is required to analyse much lower voltages then you can use the range ±2.4V that allow a minimum noise around 8 mVpp. The ±2.4V is linear just in the range -0.5V to +2.4V.

Test with a Triangle wave in the range ±2.4V:

Issues

Voltage Drift
The most relevant issue of this device is the voltage level drift over the time. The producer indicate to use the device after some minute from the power on to let it stabilize. On HScope it is require a regular calibration of the Zero Level on both channels to avoid errors up to 50mV on readings.
