BP – Bottom-Track Pings per Ensemble
Purpose Sets the number of bottom-track pings to average together in each data ensemble.
Format BPnnn
nnn = 0 to 999 pings
Range
Default BP0
In firmware versions 11.06 and earlier, the default is BP1.
Recommended Setting. The default setting for this command is recommended for most applications.
Description BP sets the number of bottom-track pings to average together in each ensemble before
sending/recording bottom-track data.
The H-ADCP interleaves bottom-track pings with water-track pings (see
Pings). If BP = zero, the H-ADCP does not collect bottom-track data. The H-ADCP automatically
extends the ensemble interval (TE) if BP x TP > TE.

BR - Resolution

Purpose Sets the vertical depth resolution.
Format BRn
Range n = 0 to 2 (see description)
Default BR1
Recommended Setting. The default setting for this command is recommended for most applications.
Description BR sets the vertical depth resolution as a percentage of the overall range detected; the
lower the resolution, the finer the depth reading. With BR0 set, if you had a depth of 100
meters, then the depth would read 100 meters until you passed 104 meters. If you had
BR2 set, then it would change when you reached 101 meters. Setting a higher resolution
(e.g. 1%) results in longer ping times.
BR0 = 4%
Resolution Setting Limitations:
1. Minimum RSSI Bin Size – The RSSI sampling interval cannot be smaller than the minimum RSSI
bin size (for example, 5 cm for a 1200 kHz system). This means that you get the resolution that
you command in % or 5 cm (for the above example) - whichever is larger. The minimum RSSI bin
sizes vary with system frequency according to the following table:
Frequency
300
