parameters, either numerical, alphanumeric or enumerated, are shown between greater than and less than symbols. I.e.
<parameter>.

4.2 Receiver Emission Tests
Much of the testing focused on the receiver can be accomplished by enabling ETERNA2’s radio to receive for an extended
period of time using the following sequence:
Power up ETERNA2 and connect to the CLI port. Enter the following command
> radiotest on
Reset or power cycle ETERNA2 and enter the following command
> radiotest rx <chanMask> <time>
Where <chanMask> would nominally be set to 0x0001 (low) , 0x0080 (mid) or 0x4000 (high) and <time> in seconds..
This sequence enables testing of:
• Receiver Conducted Spurious Emissions Operating (EN 300 328)
• Receiver Radiated Spurious Emissions Operating (EN 300 328, FCC 15.109)
• AC Conducted Emissions (FCC 15.207)
After completing tests that require radiotest commands (tx and rx) use the radiotest off command to return the device to it’s
normal state:
> radiotest off
Reset or power cycle ETERNA2.
4.3 Transmitter Power and Spectral Tests
Much of the testing focused on the transmitter can be accomplished by enabling ETERNA2’s radio to continuously transmit a
modulated signal using the following sequence:
Power up ETERNA2 and connect to the CLI port. Enter the following command:
> radiotest on
Reset or power cycle ETERNA2 and enter the following command:
> radiotest tx cm <chanMask> <power>
Where <chanMask> would nominally be set to 0x0001 (low) , 0x0080 (mid) or 0x4000 (high) and <power> to 8, the
highest output power setting used in the OEM product.
