TRACE_GRAPH_TYPES Graph types for all 4 traces. This uses a bit mask
shift, where the bit shift mask is defined as:
GRAPH_TYPE_BIT_SHIFT 16
GRAPH_TYPE_BIT_MASK 0xFFFF
DOMAIN Active Trace domain type, where:
0 is frequency domain,
2 is for distance domain
TRACE_DOMAIN_TYPES Domain types for all 4 traces. This uses a bit
mask shift, where the bit shift mask is defined as:
DOMAIN_TYPE_BIT_SHIFT 4
DOMAIN_TYPE_BIT_MASK 0xF
DOMAIN_SETUP Current Domain Setup. Available Domain setups
are:
Freq = 0, Dist = 2
TRACE_MATH_TYPES Trace Math types. This uses a bit mask shift,
where the bit shift mask is defined as:
MATH_TYPE_BIT_SHIFT 4
MATH_TYPE_BIT_MASK 0xF
Available math type are:
None = 0, Subtract = 1, Add = 2, Multiply = 3,
Divide = 4
TRACE_DISPLAY_TYPES Trace display types. Available trace types are:
Trace Only = 0, Memory Only = 1,
Trace and Memory = 2
TRACE_MEMORY_STATE For save/recall purpose.
Where 0 is Off and 1 is On.
SMITH_CHART_TYPE Current active trace Smith Chart type. Available
Smith Chart types are:
Normal = 0, Expand 10dB = 1, Expand 20dB = 2,
Expand 30dB = 3, Compress 3dB = 4
This also applies to Inverted Smith Chart.
TRACE_SMITH_CHART_TYPES Smith Chart type. This uses a bit mask shift,
where the bit shift mask is defined as:
SMITH_CHART_TYPE_BIT_SHIFT 4
SMITH_CHART_TYPE_BIT_MASK 0xF
For available types, refer to
“SMITH_CHART_TYPE”.
This also applies to Inverted Smith Chart.
