Chapter 10. Appendix 1 – Instrument/channel names

The tables in this section show the names and codes of the streamed channels along with the record names and channel codes for recorded data. The first character “x” in miniSEED channel code represents the sample rate. The possible values are shown in the table below:

F	≥ 1000 Hz to < 5000 Hz
C	≥ 250 Hz to < 1000 Hz
H	≥ 80 Hz to < 250 Hz
B	≥ 10 Hz to < 80 Hz
M	> 1 to < 10
L	≈ 1
V	≈ 0.1 Hz
U	≈ 0.01 Hz
R	≥ 0.0001 Hz to < 0.001

The “Data record names” of the seismic channels and MEMS accelerometer channels are postfixed with “A” or “B”. This notation distinguishes between the two different sample rates that is possible to select for each recorded channel. For example, the recorded streams S0AccZA and S0AccZB carry digitisations of the same signal, differing only in the sample rate.
