1 Introduction
The Signal Hound VSG60A Vector Signal Generator offers mid-range performance and agility at an
affordable price. Continuously streaming up to 40 MHz of bandwidth at up to 51.2 MSPS from a PC
or laptop virtually eliminates I/Q pattern buffer size restrictions.
The VSG60A hardware features an agile low phase noise LO synthesizer, digital baseband
oversampling with reconstruction filter, harmonic filters across the full frequency range, and a trigger
output, timed to match the RF output, for integrating the VSG60A in to test systems.
I/Q phase, amplitude, and offset are corrected across RF frequency, baseband frequency, and
temperature in our environmental chamber, and stored on the VSG60A. The software applies these
corrections in real-time.
Commands to change frequency and amplitude are embedded in the same data stream from the PC
as the I/Q data, giving the user precise timing across frequency and amplitude changes. The agile
LO can change frequency and settle in 200 µs and offers outstanding phase noise.
PREPARING FOR FIRST USE
• Install the VSG60A software, either from signalhound.com or the included CD.
• Plug in the VSG60A using the included USB Y cable by first connecting the USB 3.0 type A
connector to a USB superspeed port on your PC or laptop. Then plug in the thinner USB 2
type A connector (for extra power). Finally, plug in the micro-B connector to the VSG60A until
it is fully seated and tighten the thumb screws. Do not overtighten. You should see a solid
green LED on the VSG60A.
o Note: The VSG60A is intended for use only with the included USB cable. Longer
cables may result in an intermittent connection, especially around electromagnetic
interference.
• Launch the software.
