TA
Transfer A
Returns trace A amplitude values from the spectrum analyzer to the controller.
Syntax
( TA
Related Commands: MDS, TB, TDF.
Example
This example stores the TA results in array A.
DIM A(4011
OUTPUT 718;"IP;"
OUTPUT 718;"SNGLS;CF 300MHZ;SP 2MHZ;TS;"
OUTPUT 718;"TDF P;TA;"
FOR N = 1 TO 401
ENTER 718;A(N)
NEXT N
FOR N = 1 TO 401
PRINT A(N)
NEXT N
Description
I&SW memory area for array.
Initializes analyzer
Activates single-sweep mo& changes center
frequency and span, takes sweep.
Changes trace dutu format, outputs trace
A.
FOR NhXT loop moves each element of
trace A to the computer:
FOR NEXT loop moves the trace values
from the computer to the printer
Prints out the results.
The display unit values are transferred in sequential order (from left to right) as seen on the
screen.
Transfer of trace amplitude data should be done only as follows:
1. Select single sweep mode (SNGLS).
2. Select desired spectrum analyzer settings.
3. lake one complete sweep (TS).
4. Transfer data (TA).
This procedure ensures that the current settings of the spectrum analyzer are reflected in the
transferred data.
See Chapter 3, “Different Formats for Trace Data Transfers,” for more information about
transferring trace data. Items are separated by a comma when in TDF P format.
