User guide

The last two characters tell you the type, component, and output tap of

the stream.

• Z0, N0, E0 correspond to input channels Z, N, and E of the

digitiser's SENSOR A port, continuously output through Tap 0.

• Z2, N2, E2 correspond to the same input channels, output

through Tap 1 at a lower sample rate.

• Likewise, Z4, N4, E4 and Z6, N6, E6 correspond to Taps 2 and 3.

• Z1, N1, E1; Z3, N3, E3; Z5, N5, E5; and Z7, N7, E7 correspond to

Taps 0, 1, 2, and 3 of SENSOR B, when you connect a 6-channel

digitiser.

• 00 is the digitiser status stream (notice: zero sample rate).

• M8, M9, MA are slow-rate Mux channels reporting the sensor

mass positions for the Z, N, and E components (Section 7.4 on

page 86).

• MB is a slow-rate Mux channel used for user input, or calibration

signals on older Güralp Systems digitisers.

• MC-F are further Mux channels, used for user input or the

digitiser's internal temperature.

• X0-X7 denote the auxiliary analogue input channel on newer

DM24 units, digitized using the same tap settings as Z, N and E.

• C0-C7 denote the same input channel, when it is being used for

an input calibration signal.

• Z, N, EG-N are the channels Z, N, E0-7, respectively, when they

output triggered data.

• IB denotes digitiser Information Blocks containing user

information. Scream! tries to interpret these blocks and

automatically extracts data from them for use in WaveView

windows or Matlab extensions.

• CD, BP are digitiser streams for specialised use.

Scream! can replace these designations with more helpful names if

you wish: see Section 4.4.2 on page 49.
