2-6 Analog and Step Sweep Commands Programming with GPIB Commands

Special Step Sweep
This special step sweep provides for a step sweep that has non-equally spaced steps. It can be used in any of
the available sweep ranges (F1-F2, F3-F4, Full, F0-F, F1-F, F5-F, and F6-F). The start frequency in this
sweep must be equal to the first frequency programmed with the ZL(x) command (Section 2-17). The
intermediate steps can be programmed to be any frequency within the range of the programmed sweep.
Programming Note:
The SP1 command can be used with the dual step sweep mode.
Figure 2-5 shows an example of special step sweep programming.
For this example, assume a frequency sweep of 3 GHz to 10 GHz, with steps at 3, 6, 8, 9, and 10 GHz.
Sample Coding in BASIC
10 OUTPUT 705; “ZL000 3GH 6GH 8GH 9GH 10GH ZEL”
20 OUTPUT 705; “F1 3GH F2 10GH SNS 4SPS”
30 OUTPUT 705; “SP1 SSP SF1"
Explanation of Code:
Line 10 sets up the step frequencies.
Line 20 sets start and stop frequencies and number of steps (frequency points – 1).
Line 30 set the signal generator to SP1, Step Sweep, and F1-F2 sweep range.
