Example Closing Channel Path

[ROUTe:]PATH[:COMMon]?PATH2,1

[ROUTe:]PATH[:COMMon]?<comm>,<channel> returns either a 1 or a 0 indicating whether the specified path is closed (continuity exists) or open (the signal path is broken). <comm> is a 2-digit number and <channel> is a 3-digit number.

Parameters

NameTypeRange of Values

<comm> numeric

<channel> numeric

Comments Continuity Results. The output buffer contains an unquoted string signifying the result: 0 = the specified path does NOT have continuity or 1 = the specified path DOES have continuity

Command is Hardware Readback. PATH? is a hardware readback command. It returns the current state of the hardware controlling the specified path. PATH? does not account for a failed relay.

NOTE Use PATH? to determine if a path is closed. Closing one path may open another path if both paths use the same relays. See Chapter 1 to determine if this might happen.

Invalid Values. Invalid <comm> and <channel> values or combinations may cause one of the following errors:

2001, “Invalid Channel Number” for invalid channel< >

2023, “Invalid Common Bank Number” for invalid comm< >.

2024, “Invalid Source Bank Number” for invalid channel< >

2025, “Invalid common-source combination” for invalid combination of <comm> and <channel> parameters.

*RST Condition. Channel bb0 connects to COM bb for all 3-to-1 multiplexer banks. This is equivalent to PATH bb,bb0 (where bb is the <comm> number).
