552 N1911A/1912A P-Series Power Meters Programming Guide
BLUetooth
The Bluetooth set- up provides:
• Average power in a Bluetooth DH1 data burst.
• Peak power in the same burst
• Display of RF pulse in one timeslot
The measurement is started by detecting the Bluetooth RF burst using the
internal RF level trigger. The internal trigger is set to –20 dBm.
Time- gating is used to measure the peak and average power in a single
Bluetooth DHI data burst which lasts for 366 us. The DHI burst does not
occupy a full Bluetooth timeslot, which lasts for 625 µs.
The following table shows the power meter presets when <character_data>
is set to BLUetooth. Commands not listed are preset according to their
DEFault values (for further information refer to Table 12- 26):
