Power Supply Ripple
The following are the minimum requirements to avoid module damage and to ensure performance and
regulatory specifications are met. Certain local regulatory specifications may require tighter specifications.
3.0 to 5.5 VDC
Less than TBD mV pk-pk ripple all frequencies,
Less than TBD mV pk-pk ripple for frequencies less than 100 kHz,
No spectral spike greater than TBD mV pk-pk in any 1 kHz band.
Idle DC Power Consumption
When not actively transmitting, the ThingMagic M3e module falls back into one of 3 idle states, called
“power modes”. There are 5 enumerated idle power modes defined in the API, but the M3e module only
supports 3 options, so three of the settings behave identically. Each successive power mode turns off more
of the module’s circuits, which must be restored when any command is executed, imposing a slight delay.
The following table gives the power consumption levels and the delay to respond to a command for each.
See Idle DC Power Consumption
for details.
