BLE Transmitter Test Items
22.1.4 Quick Test(POW+MOD+Fc)
1. Objective: To measure simultaneously three TX test items -- output power, modulation characteri
stics, carrier frequency offset, and drift -- within a shorter period of time
2. Test Procedure:
A. The DUT transmits LE test packets with MAX_TX_LENGTH octet packet payload consisting of
a repetitive sequence of 0F hex octets (11110000 bin in transmission order).
B. Set LE test packet length of DUT to the longest that DUT supports and set number of packet
between 1 ~ 10 that is sufficient to production. Duration of test would take for a while if nu
mber of packet is set to long. Therefore, set the least measurement value that is confident in
order to shorten duration of test.
C. DUT transmits at maximum power.
D. Set the instrument, as in the following table.
E. Measure in the same procedure of 22.1.2 Modulation characteristics(TP/TRM-LE/BV-05-C) .
F. Measure in the same procedure of 22.1.3 Carrier frequency offset and drift(TP/TRM-LE/BV-0
6-C) .
Parameter DUT MTP200B
TEST_METHOD TEST_MODE
TEST_CASE POW+MOD+Fc
CH_NUM 0 ~ 39 Same channel as of DUT
NUM_PACKET 1 ~ 10
Packet Length(octets) 37(255 for BT v4.2 or more)
Payload Type 11110000(f1)
10101010(f2)
For the test, conduct the test twice while changing the packet type in DUT. In the first test, set
the packet type as “11110000” and measure dF1. In the second test, set the packet type as “10
101010” and measure dF2 and dF2max.
