Saving a Waveform’s Settings & Parameters
Viewing and Modifying File Header Information
The following example uses the factory–supplied waveform file RAMP_TEST_WFM.
1. From BBG media, select the waveform RAMP_TEST_WFM:
a. Press Mode > Dual ARB > Select Waveform.
b. In the Segment On column, highlight the waveform RAMP_TEST_WFM.
c. Press Select Waveform.
2. Open the Header Utilities menu:
Press More > Header Utilities
The Figure 8-5 shows the default file header for the factory–supplied waveform
RAMP_TEST_WFM. The Header Field column lists the file header parameters; use the Page
Down key to see them all.
The Saved Header Settings column shows that most of the settings are Unspecified.
Unspecified means that there is no setting saved for that particular parameter.
The Current Inst. Settings column shows the current signal generator settings. In this
example, these are the settings that you will save to the file header.
AWGN: State Indicated whether real–time noise is on (1) or off (0) (see page323).
AWGN: C/N Ratio Carrier to noise ration, in dB (see
page328).
AWGN: Carrier BW Bandwidth over which the noise power is integrated, in Hz (see
page328).
AWGN: Noise BW Bandwidth of the noise, in Hz (see
page328).
AWGN: Carrier RMS The carrier RMS across the carrier bandwidth (see
page328).
Phase Noise State Indicated whether phase noise is on (1) or off (0) (see
page332).
Phase Noise F1 The start frequency for the level mid–frequency characteristics (see
page332).
Phase Noise F2 The end frequency for the level mid–frequency characteristics (see
page332).
Phase Noise Lmid The amplitude for the level mid–frequency characteristics (see
page332).
Modulation Filter The real-time modulation filter type selected (see
page232).
Over–Range Protect Indicated whether DAC Over–Range Protection is on (1) or off (0) (see
page336).
Unique Waveform Id 0 = no Id; once an Id is assigned, it cannot be changed.
License Required Indicates whether a license is required to play the waveform. See also: “Viewing Options and
Licenses” on page49
Can be Read Out Indicates whether the waveform can be queried through SCPI or FTP.
