Quantisation of I and Q signals is selectable from 1, 2 or 3 bits per signal. Depending on the combination of channel bandwidth and quantisation, LabSat 3 Wideband will adjust the number of available RF channels to keep the record data bandwidth within a rate that ensures continuous file transfer.
LabSat 3 Wideband samples and stores the antenna signal at very high speed. When recorded RF signal is replayed by LabSat 3 Wideband into a standard GNSS receiver, such as a portable navigation system, the receiver will accept the signal as live, including all the velocity, delays and multipath effects.

LabSat 3 Wideband features 90 dB of attenuation control over the nominal signal output. This is adjustable in 1 dB steps. During replay, Pressing the 'DOWN' arrow will increase attenuation resulting in a lowering of the RF power output.
Record operation LabSat 3 Wideband uses an internal SSD (Solid State Drive) memory for storage and playback of GNSS data. This is formatted in an EXT4 linux format. LabSat 3 Wideband is supplied with a magnetic mounting GNSS antenna. The antenna is an active device with approximately 28 dB of gain.
Page 20
There are a number of GNSS systems currently in operation or in a test phase. LabSat 3 Wideband provides preselected frequencies to cover various GNSS signal recording requirements. The frequencies listed and the number of available channels depend on the required signal resolution and bandwidth. For example, it is possible to record 3 separate RF channels of 56 MHz each using 1 bit quantisation but if 3 bit quantisation is required at 56 MHz bandwidth, only one RF channel will be available.
Page 23
To maximise battery life during recording, LabSat 3 Wideband has a power save mode which is enabled by default in the setup menu. Power save mode recognizes when running from battery power and will dim the display backlight and power-down the internal monitor after 30 seconds of user inactivity.

The example below shows the folder layout on a LabSat 3 Wideband SSD. The LabSat internal SSD can use multiple folders. When folders are detected, LabSat 3 Wideband will display them in a similar fashion to a PC using the DIR indicator.
When 'Export Config' is selected (Menu > Setup > Export Config) a file called settings.txt will be placed in the root directory of the LabSat 3 Wideband internal SSD. The settings.txt file contains details of the LabSat's current configuration, an example of this file can be seen below.

09 - LabSat3W Digital Channels There are 4 channels available for external digital data capture LabSat 3 Wideband. Recorded digital channel data is synchronized to each sample of recorded RF data; the maximum input frequency for each channel is 1 MHz.
LabSat 3 Wideband is capable of listening to, and recording data from, two separate CAN networks. Dual channel CAN Bus data recording with LabSat 3 Wideband can be achieved in two ways. Depending on the mode selected, the CAN signal will be either digitized and re-created on a raw bit level or decoded and recorded in a time-stamped text file. The CAN mode operation is selected under the menu option ‘CAN’...

To enable the digital input for recording, go to Menu > Setup > Digital, select one of the four channels and then enable the tick against DIGI 1 or DIGI 2 in the signal list. Then, during recording, LabSat 3 Wideband will record the state of DIGI 1 or DIGI 2 (pin3 or pin 8 of the expansion connector).

When ‘Ext Sync’ is enabled within the LabSat 3 Wideband menu, the DIGI2 pin on the expansion connector can be used to pause record or replay allowing synchronisation of multiple LabSats or simply a remote trigger to record/replay. This is achieved when a low voltage (0 V) is applied, the DIGI pin is internally pulled up to approximately 5 V, so it is possible to pause the record or replay activity simply by connecting the DIGI input to GND via a switch.

SatGen software is a powerful tool for defining and creating RF playback scenario files for use with the LabSat Simulator. For many applications, LabSat 3 Wideband can record and playback real world, live sky data, but there may be times when you need a more controlled, user definable signal. When this is the case, SatGen provides all of the tools necessary to create a predictable, stable and accurate RF output from LabSat.

(DUT) performs. Of course, LabSat 3 Wideband can record and replay live data, but creating an artificial scenario allows you to precisely control the data content, and create a ‘gold standard’ file for carrying out true comparisons between receivers. From your bench you can try different acceleration levels, crossing different time zones, the equator, leap second roll-overs and many hard to replicate tests.
