To set the parameters, first click on the line for the channel whose parameters you
want to set. The line will be highlighted. Next, click on an item in the line to display
a list of selectable options. Choose the desired item from that list.
Double-clicking on the line of the channel to be set displays a dialog box. This dia-
log box contains settings additional to those in the Parameters window: for exam-
ple, you can perform zero balancing or calibration for some signal conditioners. For
details, see Amplifiers.
Notes on RANGE selection
The A-to-D converted value can range from –131% to +131% of the selected
input range, but the input margin is about ±120%. Select a range so that the
input will not exceed ±120%.
1. Parames Save
The
Parames Save
button saves the parameter settings as a .prm file or .txt file.
2. Parames Load
The Parames Load button reads a .prm file. Before reading, insert the same
medium that was used when the prm file was saved into the same slot. When
read, the filename is displayed in the
File
box (
3
). If you then click
OK
in the
Parameters
window, the contents of the file will be set in the GX-1 main unit.
4. Base Sample Freq
The Base Sample Freq entry determines the sampling frequency common to all
channels. When you select the option
Multi Sampling
, you can also set a 10
times the Base Sample Freq for each slot. Select
External
for external sampling.
Notes on external sampling
• The value [sampling-frequency x number-of-channels] must be 3,200 kHz or
lower.
• Bar graph display is possible when the external sampling frequency is lower
than 50 kHz. FFT display is disabled in external sampling. In waveform dis-
play, select both channels of slots. The time axis of waveform is fixed to one
second.
• When level trigger is used in conjunction with external sampling, the sampling
frequency must be 100 kHz or lower.
• When the external sampling frequency is low, do not click Start button before
the waveform is displayed. If you start recording before the waveform is dis-
played, the data may become “0”.
▼
Enable both channels of a slot.
▼
Filter cutoff frequency is set slot by slot, not
channel by channel.
▼
This dialog box can be also displayed by high-
lighting a line of a channel and then clicking on
the
Property
button.
▼
A .txt file cannot be loaded by the
Parames
Load explained below.
▼
An error occurs if the .prm file contents con-
flict with the currently installed signal condi-
tioners.
▼
The unit for k (kilo) in this box is determined
by the
Count
setting (from the Setup menu,
choose System ). The unit can be 1,000 or
1,024.
▼
The value [sampling-frequency
x
number-of-
channels] cannot exceed 3,200 kHz. When
recording to an AIT or in real-time transfer, it
cannot exceed 1,500 kHz. To an MO, it cannot
exceed 200 kHz, and to a PC card 50 kHz.
