18 Getting S tarted N9061A Application De scription N9061A Application Description The N9061A application is the re mote language compatibility suite for the Agilent T echnologies X-Series of signal analyzers.
19 Getting S tarted Document ation for the N9061A application Documentation for the N9061A application Signal Analyzers with N9061A When you purchase your X-Series signal analyzer with the Remote Lang.
20 Getting S tarted N9061A General Rules a nd Limit ations N9061A General Rules and Limitations The N9061A application has been de signed to emulate as closely as possible the operation of the specified spectrum analyzers. It is not, however , intended as an abso lute direct replacement for these analyzers.
21 Getting S tarted N9061A General Rules and Limit ations Markers The N9071A applicatio n emulates the behavior of le ga cy products. If someone uses a marker s tate which is not available in the legacy instrument, further ma rker behavior is undefined until instru ment preset.
22 Getting S tarted N9061A General Rules a nd Limit ations Supported Commands Only a subset of the 8566 /8568/8560 Series co mmands is supported in th is application (through a GPIB interface). The list of supp orted commands was determined by f eedback from our cu stomers combined with technical considerations and constraints.
23 Getting S tarted Hardware and Firmware Requirement s for N9061A Hardwar e and Firmware Requir ements for N9061A One of the following Agilent si gnal analyzers is required to run the N9061A application.
24 Getting S tarted Hardware and Firmware Requirement s for N9061A 8562E/EC 30 Hz 13.2 GHz 8563E/EC 9 kHz 26.5 GHz 8564E/EC 9 kHz 40.0 GHz 8565E/EC 9 kHz 50.
25 Getting S tarted Inst alling the N9061A application Installing the N9061A application Remote language compatibility for the 8566/8 568/8 56 0 Series of analyzers is a licensed application on the X-Series analyzers. The op tion for 8560 series is N9061A-2 FP and the option for 8566/8568 is N9061A-1FP .
26 Getting S tarted Inst alling the N9061A application A license key is usually for one instrument model/ser ial number combination. The license key can only be installed on that instrument. License Installation Procedur e over USB 1. Redeem the Option Upgrade Entitlement Certificate by following the instructions on the Certificate.
27 Getting S tarted Setting up N9061A on the X-Series Analyze r Setting up N9061A on the X-Series Analyzer Figure 1- 1 is an example mode menu map showing th e N9061A (Remote Language Compatibility) application selection on your signal analyzer .
28 Getting S tarted Setting up N9 061A on the X-Series Analyzer Then, to select the legacy analyzer you wish to emulate, press the Mode Setup hardkey on the front panel.
29 Getting S tarted Setting up N9061A on the X-Series Analyze r The legacy instrument se lections are as follows: 8560E/EC Selects the 8560E/EC remote programming language and sets the response to the remote programming command ‘ID?’ to HP8560E .
30 Getting S tarted Setting up N9 061A on the X-Series Analyzer NOTE Setting the remote language to anything other than ‘SCPI’ does not af fect the response to the SCPI command ‘*IDN?’ This command will still return the model number and firmware version number of the X-Series signal analyzer .

32 Getting S tarted Setting up N9 061A on the X-Series Analyzer Cmd Err or Tu r n i n g Cm d Error On or Off enables or disables the disp lay of the "CMD ERR" error messages. The default setting is On. The error message appears in the Message bar and also can be querie d using “ERR?”.
33 Getting S tarted Setting up N9061A on the X-Series Analyze r Logging The N9061A application allo ws the logging of errors. These errors comprise details of command errors and legacy commands that have been received but are not supp orted by the N9061A application.
34 Getting S tarted Setting up N9 061A on the X-Series Analyzer Refresh T o update the log page with new entries, select Refresh . Clear Log The Clear Log softkey clears the error log. The log can only be cleared by usin g th e Clear Log fu nction and ca nnot be cleared on power-up, remote language switch or mode switch.
35 Getting S tarted Setting up N9061A on the X-Series Analyze r Prefer ences The Preferences menu allows you to configure some analyzer settings when in remote language compatibility mode. Figure 1-4 shows the Preferences menu ma p that is accessed by selecting the Mode Setup hardkey on the fron t panel and then selecting the Prefere nces softkey .
36 Getting S tarted Setting up N9 061A on the X-Series Analyzer Sweep T ype Rules Sweep T ype Rules changes the Auto rules fo r determining whether the in strument uses FFT or Swept mode (this can be manually overri dden). FFT mode of fers substantia lly faster measurements in some cases.
37 Getting S tarted Setting up N9061A on the X-Series Analyze r Restore Mode Defaults Resets the state for the currently active mode by resetting the mode pe rsistent setting to their default values and by performing a mode preset. This function will never ca use a mode switch.
38 Getting S tarted Running Sof tware that Requires SCPI Comma nds Running Software that Requir es SCPI Commands When a legacy remote language has been selected, you only have access to a very small subset of SCPI commands.
39 Getting S tarted Running Sof tware that Requires SCPI Commands [:SENSe]:RLC:BANDwidth:LIMit ON|OFF|1|0 [:SENSe]:RLC:BANDwidth:LIMit?
