Saving a Waveform’s Settings & Parameters
Viewing and Modifying 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 9-5 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
page 341
).
AWGN: C/N Ratio Carrier to noise ration, in dB (see
page 346
).
AWGN: Carrier BW Bandwidth over which the noise power is integrated, in Hz (see
page 346
).
AWGN: Noise BW Bandwidth of the noise, in Hz (see
page 346
).
AWGN: Carrier RMS The carrier RMS across the carrier bandwidth (see
page 346
).
Phase Noise State Indicated whether phase noise is on (1) or off (0) (see
page 350
).
Phase Noise F1 The start frequency for the level mid–frequency characteristics (see
page 350
).
Phase Noise F2 The end frequency for the level mid–frequency characteristics (see
page 350
).
Phase Noise Lmid The amplitude for the level mid–frequency characteristics (see
page 350
).
Modulation Filter The real-time modulation filter type selected (see
page 263
).
Over–Range Protect Indicated whether DAC Over–Range Protection is on (1) or off (0) (see
page 354
).
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 page 37
Can be Read Out Indicates whether the waveform can be queried through SCPI or FTP.
