Possibly you would like to restore or repeat a measurement you performed under spe- cific conditions on the R&S EVSG1000. Or you would like to troubleshoot a measure- ment and require a defined instrument state to detect the precise cause of the error. In these cases, you can store and recall instrument and measurement settings.
Page 216
Preset Access: [Preset] > "Preset" When delivered, the R&S EVSG1000 has a default configuration. You can restore this defined initial state at any time as a known starting point for measurements. Presetting is often recommendable as a first step in troubleshooting when unusual measurement results arise.

Rename Renames the selected UserPreset. 8.2 Recording Measurement Data During a measurement with the R&S EVSG1000, the input signal is captured and vari- ous results are calculated and displayed on the screen (see Chapter 2, "Measurements Results", on page 48).
32 bit each, in little endian and signed integer format. The I/Q data level is aligned to the RF input signal of the R&S EVSG1000. That is: 0 dBm correspond to a magnitude value of 0x10000000 (hexadecimal). Each sample requires 8 bytes of storage, which adds up to 1 MB per second.
® Data Management R&S EVSG1000 Recording Measurement Data You can use the I/Q data to analyze the signal in external software, for example, or to reproduce the signal on a signal generator. 8.2.3 Recording Settings Access: "Config" >"Rec Config" Access VNC: [s] > [F7]...

Page 224
Internally, the screenshot files are named "Screenshot_", followed by a consecutive number. If a USB device is connected to the R&S EVSG1000 when the screenshot is created, the screenshot is stored there directly as a .PNG file. A dialog box with the default file name is displayed.

After demodulation of the signal, the signal data is available in the baseband (BB). The R&S EVSG1000 provides this baseband signal at the Demod Out connector of the instrument. Thus, you can analyze the data with other connected devices, for example an oscilloscope.

Note: PPS input recommended. It is strongly recommended that you connect the PPS signal of the GPS receiver to the "PPS In" connector of the R&S EVSG1000. Although it is possible to store data on the R&S EVSG1000 without the PPS signal connected, this may lead to an incorrect assignment of the stored data to the actual GPS time.
