To sweep external sampling clock
When you choose
External
from
Base Sample Freq
,
Sweep
check box
will appear. Check the box to sweep the external sampling clock. If not
checked, the input frequency must be constant.
Note the following when sweeping the sampling clock.
• The swept frequency must be 20 kHz or lower. The external sampling frequen-
cy must be constant if it is higher than 20 kHz.
• Sweep the clock continuously. Stepwise change may cause recording impossi-
ble.
• When the external sampling frequency is low, it takes some time for the wave-
form to be displayed after pressing the
Rec Standby
button. (ex. 2 minutes
and 30 seconds at 1 kHz)
• Bar graph display is disabled in sweep mode.
5. Multi Sampling
Turn on the
Multi Sampling
check box to perform multi-frequency sampling,
which enables you to set a 10 times the Base Sample Freq for each signal condi-
tioner (that is, for each 2 channels). When the sampling frequency of one channel
is changed, the sampling frequency for the other channel of the slot also changes.
Notes on Multi-sampling
• The Base Sample Freq must be 20 kHz or lower.
• Multi-sampling is not possible when using external sampling.
• A data file recorded by multi-sampling cannot be read by commercially avail-
able analytical software.
• The voice memo is sampled at the Base Sample Freq when it is recorded in the
MIX mode.
• Phase differences among channels do not occur in recorded data. However, in
reproduced waveforms, phase differences occur.
• When the Base Sample Freq is 5 Hz or lower, reproduced waveforms may be
distorted.
6. MISC
Unique settings for each signal conditioner can be set in MISC1, MISC2, and
MISC3 for each channel. This area (6) displays the MISC contents. The exam-
ple shows that MISC1 of the DC amp for the channel 1 is the cutoff frequency.
7. Same Setting
After highlighting a line for a channel by clicking on it, if you then click the
Same Setting
button, the same settings will be set for all channels of the same
type of signal conditioner.
