IQ Data: Toggles the IQ Data (vectors) on or off and enables the transfer configurations below. The IQ vectors from Signature give you the most freedom to make complex measurements, such as FFTs or demodulation, and allow larger data sets. When IQ Data is selected, Signature does not
Advanced Tabdisplay trace data and the MATLAB Setup dialog must be left open.
Sample Rate (S/s)/BandWidth (Hz): Selects the following Sample Rate and Bandwidth, (S/s)/(Hz):
With Option 22:
50M/25M, 50M/20M, 25M/10M, 12.5M/5M, 6.25M/2M, 3.125M/1M, 2M/800K, 1M/400K, 500K/200K, 400K/150K, 200K/80K, 100K/40K
Without Option 22:
21.4M/10M, 21.4M/5M, 12.8M/3M, 8.56M/2M, 4.28M/1M, 2.14M/500K, 1.284M/300K, 856K/200K, 428K/100K
Capture Time: Sets the capture time. Ranges from 2 µs to 1.28 s, depending on the sample rate/bandwidth selection.
Sweep Mode: Toggles between continuous or single sweep modes and starts a single sweep. Sweep mode is disabled when handshaking is enabled.
Input: Toggles between Wideband RF Input, Narrowband RF Input, Wideband Single I/Q or Wideband Diff I/Q.
Impedance: Toggles between 50Ω or 1MΩ.
MATLAB Handshake: Toggles the MATLAB handshaking on or off. Handshaking allows you to know when Signature is finished making a measurement and can be useful for such things as storing or averaging multiple traces, where you need to know when the trace data is new. When handshaking is selected, sweep mode is disabled.
In the MATLAB application, the following script:
Signature_Control(‘StartSweep’)
is used to initiate a sweep when handshaking is toggled On.

Note: The connection to MATLAB can only be made when Option 40 is installed. Option 40 comes with a trial version of MATLAB, from The MathWorks, that may need to be activated. The full MATLAB software is not supplied with Signature and must be purchased separately.
Install MATLAB with any of its configurations and licensing option onto the “C:” drive in Signature. It is best to install
MATLAB into the default directory.
