<Tr>={[1]|2|...16}
<Ch>={[1]|2|...16}
<char> Specifies parameter:
| S11, S21, S12, S22 | S-parameter | 
| A, B or T1, T2 | Test receiver | 
| R1, R2 | Reference receiver | 
| AUX1, AUX2 or V1, V2 | DC Voltage | 
{S11|S21|S12|S22|R1(n)|R2(n)|A(n)|B(n)|V1(n)|V2(n)},
Where n is the stimulus port number
Depends on the trace number.
Measurement > S11 | S21 | S12 | S22 …
Measurement > Absolute > {A(1) | B(1) | R1(1) | A(2) | B(2) | R2(2)}
