Set Site Master VNA Trace Overlay – Control Byte #34 (22h)
Description: Setup trace overlay operation and trace for VNA modes.
Bytes to Follow: 2 bytes
1) Trace Overlay Operation
00h = Off
01h=On
2) Trace on which to Perform Overlay Operation (1 to 200)
Site Master Returns: 1 byte
1) 255 (FFh) Operation Complete Byte
224 (E0h) Parameter Error: Invalid Trace Overlay Operation

Set SPA A/B Trace – Control Byte #35 (23h)
Description: Defines traces “A” and “B” for SPA mode.
Trace A is always the currently measured data (with or without trace math). It is always visible.
Trace B is always stored data and may come from a saved sweep or a previous “A” trace. There is no default for trace B.
Trace B can be ON (visible) or OFF.
Bytes to Follow: 3 bytes
1) “A” trace display (00h = A only, 01h = A-B, 02h = A+B)
2) “B” trace status (00h = Off, 01h = On)
3) “B” trace number
0 = save current “A” data into “B” buffer, use that as “B”
1-200 = trace number
255 = no “B” trace defined
Site Master Returns: 1 byte
