Setting CR95HF to continuous transmit and max power for emissions testing?

RFetc

For FCC testing, I'll need to configure the CR95HF to:

  • continuously transmit
  • operate at max power

I'm basing this off of a paragraph in the corresponding FCC document (ID YCPDEMOCR95HF):

Equipment under test operating condition:

The equipment under test is blocked in continuous modulated transmission mode, at the highest output power level at which the transmitter is intended to operate.

Does the CR95HF have a special test mode to accomplish this? Or if it must be done manually, how do I set this up?

​Hi,

I believe the "continuously transmit" requirement only applies to full duplex transceiver whereas NFC readers are half duplex. Therefore, this requirement is likely not applicable for NFC transceivers.

Regarding the second requirement (max power), the output power is fixed for a given operating voltage.
