====== Jalapeno power consumption ====== 

  * All power consumption tests are done with 8DEV_3001_Jalapeno_DVK. Both Gold (receiving) and DUT(transmitting). 
  * Power measurement are done with UNI-T UT658 USB power meter.

===== Base power consumption, no wireless throughput =====
^Work Mode  ^ Power Consumption, //W// ^
| module on, no ETH port plugged in, radios Down | 2.2 |
| 1 ETH port plugged in | 2.5 |
| 2 ETH port plugged in | 2.7 |
| 2 ETH port plugged in, using as bridge and 1G throughput | 3.1 |
| 2 ETH and 2G radio Up | 3.2 |
| 2 ETH and 5G radio Up | 3.5 |
| 2 ETH and 2+5G radios Up | 4 |
|Disabling USB|Module has no way to externally disable USB, disabling driver was not tried|

===== Changing transmit power =====
  iw dev <dev name> set txpower <limit/auto/fixed> <txpower in mBm>

  * <dev name>: device name, wlan0 for 2G radio, wlan1 for 5G radio
  * <txpower in mBm>: transmit power is set in mBm (mili Bell miliwat), mBm to dBm ratio is 100:1
  * iw --help for more help


=====CPU Frequency=====
=== To change CPU frequency ===
  echo <frequency> > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
  echo <frequency> > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
 
  * Available frequencies are: 200000 500000 718000

=== To see current CPU frequency ===
  cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
  
 =====Low power mode for RF power amplifier. Requires factory recalibration=====

^ Tx Power, //dBm// ^ Throughput(5G+2G), //Mbps// ^ TCP/UDP ^ Voltage, //V// ^ Current, //I// ^ Power, //W// ^
|MAX -10|300+98|TCP|5.26|1.1|5.7|

This mode sets the power amplifier to power save mode, reducing the output power by 10 dBm. This option requires factory recalibration to function properly.
