Chapter 4. Printing Data
4.7 Printing Signal
Array Data
Use the SGNLS submenu to print signal array data, to help diagnose certain
problems. To print the signal data, see Figure A-7 on page A-7 and complete the
following steps:
IMPORTANT: Make sure that a printer has been properly set up before proceeding
with this section.
1. To access the Print Menu , press the [PRNT] key.
Note:
The
Print Menu
is not protected by the security feature and a password is
never required to access this menu.
2. Press the [
←
] or [
→
] key to display the option bar shown, and then press [F2] to
select the SGNLS submenu.
3. Press the [F1]-[F3] keys to select the desired
Signal Array
data to print. To abort
the procedure, press the [EXIT] key.
Note:
The
SIGNL
option causes the raw signal array data to print, while the
CROSS
option causes the cross-correlation data to print. The
BOTH
option prints
both sets of data.
After the desired print selection has been made, the Model GC868 returns to the
standard data display screen and normal measurement taking. The specified signal
array data is printed continuously, until it is manually stopped. To terminate signal
array printing, use the STOP submenu, as described earlier in this chapter. A portion
of a typical printout is shown in Figure 4-6 below.
Figure 4-6: A Typical Signal Array Printout
The data printed via the SIGNL submenu consists of 1024 lines, each of which lists the
following three values:
• Index - this is the printout line number, which locates the data point within the
complete body of data.
• Upstream - this is the amplitude of the signal from the upstream transducer at
the listed index number.
• Downstream - this is the amplitude of the signal from the downstream
transducer at the listed index number.
