The Trace and Scan menu defines the four data traces and the data
buffer usage. The sample rate and scan time for data storage and
sweeps are set in this menu. See the Data Traces and Trace Scans and
Sweeps discussion in the Screen Display Operation section for more
information.
The SR850 collects and displays data in the form of traces. There are
four data traces which may be defined. Each trace is defined as A•B/C
where the parameters A, B and C are chosen from X, Y, R, , Xnoise,
Ynoise, Rnoise, Aux Inputs 1-4 (rear panel), Frequency, and unity (1). C
can also be any quantity squared.
Only data traces may be displayed. In order to display the quantity X, a
trace must be defined to be X and then displayed (see the DISPLAY/
SCALE menu).
When the unit is reset, the traces are defined as
Trace 1 = X, Trace 2 = Y, Trace 3 = R, Trace 4 =
Pressing this key selects Trace 1, 2, 3 or 4. The selected trace's defini-
tion and storage mode is displayed below the trace selection. Only the
selected trace's definition and storage mode may be changed.
A B / C Pressing this key highlights the boxed parameter (either A, B or C in the
equation A•B/C). The highlighted parameter may be changed using the
knob. Pressing the key again highlights the next parameter and so on. In
the illustration above, the A parameter is boxed and is set to X. The
parameters B and C are both unity.
