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.
