Use PPK2 testing nrf9160 PSM and eDRX power consumption

Dear Support team,

I used PPK2 to test the PSM mode current of nRF9160 is about 7.09uA (as shown in the figure below),but the eDRX mode current has not been tested successfully.

I am using Modem FW  v1.2.3, UDP sample code of NCS v1.4.1 , nRF9160 DK v0.8.5, config to NB-IOT network ,  part of prj.conf is as follows:

```
# LTE parameters
## Network Mode / LTE category
#CONFIG_LTE_NETWORK_MODE_LTE_M=n
CONFIG_LTE_NETWORK_MODE_NBIOT=y
CONFIG_UDP_SERVER_ADDRESS_STATIC="169.254.84.149"
CONFIG_UDP_SERVER_PORT=123

## PSM
CONFIG_UDP_PSM_ENABLE=y
CONFIG_LTE_PSM_REQ_RPTAU="00100001"
CONFIG_LTE_PSM_REQ_RAT="00000000"

## eDRX
CONFIG_UDP_EDRX_ENABLE=y
CONFIG_LTE_EDRX_REQ_VALUE="0000" #"1001"

## RAI
CONFIG_UDP_RAI_ENABLE=y
CONFIG_LTE_RAI_REQ_VALUE="4"

#LOGls
CONFIG_LOG=n
CONFIG_USE_SEGGER_RTT=n
CONFIG_LOG_BACKEND_RTT=n
CONFIG_AT_HOST_LIBRARY=n
CONFIG_RTT_CONSOLE=n
CONFIG_UART_CONSOLE=n
CONFIG_LOG_PRINTK=n

CONFIG_LOG_DEFAULT_LEVEL=3

```

I saw on a Nordic PPT that the current in PSM mode can reach 4uA, which is a bit different from the 7uA I measured. Is the 7uA I measured is normal? It is 3uA different from the data on the Nordic PPT. Is this caused by the accuracy of PPK2?

Best regards,
Devin
