MT8850A / MT8852A Bluetooth Test Set Using the Script Menu
8-14 13000-000109
Testing in Standard Script Mode January 2003
Power Control Test (Standard Mode)
The power control test performs power measurement cycles on the EUT output, if the EUT
supports power control, at each of the defined frequencies (LOW, MEDIUM and HIGH).
This measurement is always performed with hopping off. The MT8850A/MT8852A can
perform the test using either loopback test control or TX test control. The default form for
this test is to use loopback. The following test is described using the default test control.
The MT8850A/MT8852A transmits a DH1 (or the operator selected packet type) packet
with a pseudo random data payload (PRBS 9). This test is performed with hopping off.
The LOW, MEDIUM and HIGH frequency sets relate to the default frequencies specified in
the Bluetooth RF test specification. The MT8850A/MT8852A allows all the frequencies to
be changed.
A power measurement cycle sets the EUT output power to its maximum and then steps
the power down to the minimum power and then up to the maximum again one step at a
time. For each power step a number of data packets are sent to the EUT and looped back
to the MT8850A/MT8852A.
When the test is performed in TX test mode only the TX
frequency settings are used since both RX and TX frequencies
must be the same.
1. Choose “Power control” 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 Power control test conditions screens are displayed.
You can change the number of cycles. In one cycle the EUT goes from maximum to
minimum power then returns to maximum power one power step at a time. You can
also change the test type and packet type.
4. Choose “Cycles”.
5. Enter the value using the keypad.
6. Choose “Test type”.
7. Press the key to switch between Loopback and TX.
8. Choose “Packet type”.
