N9061A General Rules and Limitations

Markers

The N9071A application emulates the behavior of legacy products. If someone uses a marker state which is not available in the legacy instrument, further marker behavior is undefined until instrument preset.

On systems that supported MKACT, there are 4 completely different marker pairs, each with its own information. The N9061A will store the currently active value of MKACT. If MKACT is 2 then it will use Markers 3 and 4 instead of 1 and 2.

Parsing

For 8566B and 8568B, the N9061A will remember the active function and supports UP, DN, and OA, all of which change the active function. It also supports '?', which does not change the active function.

One difference between N9061A and 8566/68 is that the 8566/68 parses a command for example CF 10.3GZ, immediately when it recognizes a complete command, in this example after the GZ. However the N9061A parses at the end of a line when it sees the line termination sequence.

Couplings

To provide the most optimized use of the X-Series analyzers, the N9061A application uses the auto coupling features of the X-Series analyzers and does not attempt to mimic the exact behavior of coupling in the legacy analyzers. To eliminate the possibilities of "Meas Uncal" errors between auto and manual values, values will default to the X-Series auto settings where applicable (for example resolution bandwidth). There are several exceptions below.

To prevent timeout errors in the legacy code, the resolution bandwidth minimum matches the minimum in the legacy analyzer. Resolution bandwidth steps and resolution, however, will be X-Series values.

The video bandwidth will couple to the resolution bandwidth according to the Video bandwidth coupling offset value, specified by the VBO or VBR command. The X-Series analyzers sets the video bandwidth according to the VBO or VBR setting, but uses the X-Series analyzers available bandwidths to prevent 'Meas Uncal' errors.

Predefined Functions

In the 8566/8568/8560 Series analyzers, a “predefined function” is an analyzer command that returns a number that can be operated on by other analyzer commands. “Predefined variables” follow the same idea, except the value to be passed as a parameter to the next command is stored in a variable.

The N9061A application does not support this type of behavior, so any commands that originally acted as predefined functions or variables, or that allowed predefined functions or variables as arguments in the 8566/8568/8560 Series no longer do so.

User-defined Functions

No user-defined functions, traces, or variables (FUNCDEF, TRDEF or VARDEF) can be used as arguments or commands in programs controlling any analyzer running the N9061A application. In addition, the behavior of certain commands that rely on the “active functions” (UP, DN, etc.) may be slightly different.
