Timing Commands
The following commands let you set the timing of various profiling functions.
Available Timing Commands
This section lists the available Timing commands.

TB = 00:00:00.00 --------- Time per Burst (hrs:min:sec.sec/100)
TC = 00000 --------------- Ensembles Per Burst (0-65535)

Timing Command Descriptions
TB - Time per Burst
Purpose Sets the interval between “bursts” of pings.
Format TB hh:mm:ss.ff
Range hh = 00 to 23 hours
mm = 00 to 59 minutes
ss = 00 to 59 seconds
ff = 00 to 59 hundredths of seconds
Recommended Setting. Special applications only.
Description The TB and TC commands work together to allow the H-ADCP to sample in a “burst
mode.” In some applications, it is desirable for the H-ADCP to ping for a short period of
time at a high ping rate (“burst”), wait for a set period of time, and then repeat the pro-
cess. You also must set the time per ensemble, time between pings, and number of pings
per ensemble.
Example Deployment timing example:
TB 01:00:00.00 (time per burst)
TC 20 (ensembles per burst)
TE 00:00:01.00 (time per ensemble)
TP 00:00.20 (time between pings)
WP 2 (pings per ensemble)
The H-ADCP will average two pings (WP-command) 0.2 seconds apart (TP-command). It then sends the
ensemble to the recorder or through the I/O cable. This process is repeated once a second (TE-command)
for a total of twenty ensembles (TC-command). After the 20th ensemble is processed, the H-ADCP sleeps
for one hour (TB-command) from the time of the first ping of the first ensemble until the second burst
begins.
