MT8850A / MT8852A Bluetooth Test Set Using the Script Menu
Maximum Input Power Test (Standard Mode)
For the EUT maximum input power test the MT8850A/MT8852A transmits a pseudo
random payload (PRBS 9) DH1 data packet to the EUT so that the EUT receives the
signal at a power level of -20 dBm. The EUT loops back the received data and a bit error
rate (BER) calculation and frame error rate (FER) calculation is performed by the
MT8850A/MT8852A test set. The test is repeated for each of the frequency ranges
selected (LOW, MEDIUM and HIGH). This test is performed with hopping off. The LOW,
MEDIUM and HIGH frequencies relate to the default frequencies specified in the Bluetooth
RF test specification. The MT8850A/MT8852A allows all the frequencies to be changed.
1. Choose Input power from the Script menu.
2. Press the
key to select or deselect this test from the script routine.
If a test is selected, the box will be filled in. If not selected the box will be hollow.
3. Press the
[Setup] soft key.
The Maximum input power test conditions screens are displayed.
You can enter the number of packets to be sent and enter the Test transmission power
value.
4. Choose “Number of packets”, and press the
key.
5. Enter the number of packets from the keypad and press the
[Enter] soft key.
6. Choose “Test TX Power” and press the
key.
7. Enter the value from the keypad and press the
[Enter] soft key.
8. Choose “Payload Pkt count”.
This setting allows the user to specify whether the count of the number of packets is
based on the transmitted or received values. The settings are detailed below.
Transmitted: The count is based on the number of transmitted packets. Due to lost
packets, this setting may result in failure to comply exactly with the
Bluetooth test specification that requires that the test should be
conducted for at least 1.6 million packets.
Received: The count is based on the number of packets actually received. This
setting will force the MT8850A/MT8852A to continue testing until 1.6
million packets have actually been measured.
9. Press the
[1 of 2] soft key to move to the second screen.
