File

New disposes the current settings and sets the software to its initial state using the current hardware configuration. The window name changes to Closed Untitled. Rename and save the new setup as a settings (.mtd) file (saving only the software parameters), or as a Quick Setup (saving the current hardware and software parameters).

	You must save the current software parameter settings before selecting File > New to prevent the loss of data.

If either a signal generator or arbitrary waveform generator are connected, they will be preset and then loaded with default settings by the software.

Open... opens a saved settings (.mtd) file. Opening a settings file configures only the waveform data parameters for use with the currently selected hardware. To use a settings file with a different hardware configuration, select Change Hardware Settings, or Run System Configuration Wizard to configure new hardware.

Use Quick Setups to open a saved settings file that includes the hardware configuration and software settings.

Save saves waveform data settings to the current filename.

Save As... saves only waveform data settings to a specified settings (.mtd) file. Settings files do not contain the hardware configuration data. To save a settings file with a specific hardware configuration, select Change Hardware Settings, or Run System Configuration Wizard to configure new hardware. When a file is saved it is added to the top of the Most Recently Used Files list.

Use Quick Setups to save the current hardware configuration with your waveform setup.

Export Waveform Data... saves an encrypted waveform file (with the .wfm file extension) to your PC. This waveform file can then be downloaded and played in licensed ESG, PSG, MXG, or EXG signal generators, M8190A arbitrary waveform generators, or ADS design libraries. If a waveform is configured, but has not been generated, this selection also generates the waveform.

To download a saved waveform to a signal generator, refer to that signal generator's Programming Guide.

Export Wideband Arb Data... exports four binary files for M9330A, N6030A, or N8241A arbitrary waveform generators that are compatible with the Arb Control Utility waveform playback function. The files include two waveform files and two marker files as follows:

filenameCh1.bin
filenameCh2.bin
filenameMkr1.bin
filenameMkr2.bin

Refer to the Export a Wideband Waveform procedure for instructions.

Most Recently Used Files displays the four most recent settings files that were either opened with Open... or saved with Save as.... The settings file used most recently is added to the top of the list. Deleting a settings file does not immediately remove it from the list. Selecting a deleted settings file displays an error then removes the file from the list.

Exit stops and closes the software. If you made any waveform setup changes, a Closed dialog box is displayed asking if you want to save the changes as a quick setup before exiting. The Closed close button performs the same function.

To save any hardware parameter changes, you must use the Save As Quick Setup button. You are not prompted to save Hardware parameter changes when closing or exiting the software unless changes are also made to the Waveform Setup parameters.

Control

Download enables you to generate and download a waveform (based on the current signal setup) to the hardware.

When a power-sensitive DUT is connected to the signal generator, ensure that the RF power is off before downloading a waveform.

Play finds the waveform specified in the Waveform Name field and plays it.

By default, this function updates all parameter settings to the hardware. You can change the default setting from the Tools menu.

Stop causes the current signal to stop playing on the signal generator and turns the Arb off.

The RF output state is determined by the Turn RF Off/On Stop parameter.

Trigger provides a software trigger to the Arb over the IO channel from either the GUI or API.

Measure IMD uses the existing signal parameters (suppression bands for multitone, notch parameters for NPR) to measure distortion products in the current waveform and display them on the GUI. Measure IMD can only be used after the waveform has been corrected.

Measure Flatness enables you to measure the relative tone power in the current waveform. Measure Flatness can only be used after the waveform has been corrected.

Real Time Update enables or disables the ability to update hardware settings immediately.

When enabled, you can change the hardware settings (frequency, amplitude, etc.) by changing the software parameter value.

When disabled (default setting), the hardware is updated by selecting Update to Instrument Upon Play or by downloading a waveform.

The Internal Arbs and the M8190A Arb also have real time control of IQ Skew and IQ gain Balance on the instrument panel. You need to enable Real Time Update to use these controls.

Play Test Signal plays a factory-generated waveform file (named TestSignal). The Test Signal contains 20 tones offset from the carrier such that you can see images and carrier leakage caused by non-ideal I/Q modulation. The Closed Test Signal bandwidth is maximized for a given system configuration and the current RF frequency.

In general, the Test Signal bandwidth is:

Arb Only Waveform Generator Configurations
N8241xA or N603xA The smaller of	(Arb Sample Rate)/2.5 or
	(Arb Sample Rate - Frequency)*2 or
	(Frequency*2)
where Frequency is the value entered in the Multitone or NPR Basic properties. The maximum bandwidth of 500 MHz occurs when the Arb sample rate is 1.25 GHz and Frequency is 250 MHz.
Internal Arb Waveform Generator Configurations
ESG/PSG internal Arb	80 MHz
MXG Internal Arb	100 MHz (80% Arb max sample rate)
External Arb Waveform Generator Configurations
ESG/PSG/MXG External I/Q	265 MHz
Wideband Arb Waveform Generator Configurations
PSG Wideband I/Q > 3.2 GHz	1.0 GHz, 500 MHz (80% Arb Sample Rate)
PSG Wideband I/Q < 3.2 GHz	400 MHz
PSG Wideband I/Q H18 < 3.2 GHz	1.0 GHz, 500 MHz (80% Arb Sample Rate)
PSG Wideband I/Q HBQ > 3.2 GHz	500 MHz
PSG Wideband I/Q HBQ, H18 < 3.2 GHz	500 MHz

Clear Correction forces the waveform to be regenerated and corrections to be remeasured on the next download.

Clear ARB Memory removes all waveforms from the Arb waveform memory. You can use this function to make room for additional waveforms if the Arb memory is full.

Clear ARB Memory does not erase waveforms stored in non-volatile memory.

System

Change Hardware Connections displays a list of saved hardware connections. This menu choice opens Closed Step 3 of the System Configuration wizard, where you can select a previously saved hardware configuration, or configure and save a new hardware setup.

Run System Configuration Wizard enables you to configure your system component connections and save the hardware configuration for later use. Use Closed Run System Configuration wizard to set up a new signal generator connection, or use Quick Setups to save and change between complete setups that include the hardware connection and software settings.

Tools

Setup Spectrum Analyzer on Play configures the spectrum analyzer to view the downloaded signal.

This property works only if a spectrum analyzer is configured in the system. Otherwise, the property is disabled.

Update to Instrument Upon Play sets all hardware parameters (signal generator, arbitrary waveform generator) to the values currently set in the application.

Turn RF Off on Stop turns off the RF output when software execution is stopped.

Use Wideband IQ Below 3.2 GHz enables or disables the wideband RF path below 3.2 GHz. This feature makes it possible to generate 1 GHz bandwidth signals below 3.2 GHz. It also provided better RF flatness below 250 MHz when using the PSG internal Arb.

Available for the PSG-D with Option H18 or 018 only; not available for the ESG, MXG or PSG-C.

This selection is hardware configuration-specific and is not saved in the Multitone Distortion settings file <filename.mtd>. The application always starts with this selection in its disabled state.

Use Shift RF Filter Switch Points improves the RF flatness of wideband signals (greater than 50 MHz) by changing the RF filter switch points. The benefit is greatest for signals below 3.2 GHz where there are several RF filters. There is no effect when using the Use Wideband IQ below 3.2 GHz feature. This setting will overwrite the PSG-D's Harmonic Filter Switch Point setting. See also RF Filter Switch Point examples.

The filter switch points are:

Normal 250, 396, 628, 1000, 1500, 2400, 4000
Switched 170, 316, 548, 920, 1420, 2320, 3120

Available for ESG and PSG-D only; not available for MXG or PSG-C.

This selection is hardware configuration-specific and is not saved in the Multitone Distortion settings file <filename.mtd>. The application always starts with this selection in its disabled state.

Display Welcome dialog lets you enable or disable the Closed welcome dialog display.
