SG6000 - A wideband RF Signal
Generator
The SG6000 family of signal
generators enables users to generate ahigh quality RF/Microwave signal in acompact package. An OLED display
and interface buttons allow frequency
selection, attenuator control, and RFoutput ON/Off without need for a hostPC. The RF output covers 7 octaves
from 25 to 6000MHz or to 12000MHz
with the optional doubled output, or to
22GHz with option Q . The produced
waveform is fully synthesized using
modern fractional N synthesis. The final
step size of the RF output varies froma maximum of ~3KHz to less than 20Hz
depending on band of operation. Thissynthesized source has its own internal
precision 10MHz TCXO oscillator andcan accept an external reference signal
if needed.
Power output level can becontrolled via internal step attenuator
over a range of 31dB in 0.5dB steps,
and also has a separate 20dB power
vernier setting. RF output power iscalibrated to a maximum output level of+10dBm. Higher output is possible
when in un-calibrated mode.

Ease of Use
SG6000 signal generators
can be controlled from the front
panel interface or by the USB port
and a host PC. The user simply
connects a PC to the SG6000, andwith provided software all settings
and functions can be remotelyoperated in real time.
Signal Generator USBOperation
With the SG6000 connectedto the PC via micro USB port,
industry standard SCPI commands
are used to fully control theinstrument. The USB port isconfigured on the host PC as a
virtual COM port. This featureallows users to control the signal
generator for automated test
applications from many different
operating systems and scripting
languages and environments.

SG6000FHarmonics
The SG6000F and SG6000PRO focus on filtering the harmonics inherent to PLL based synthesizers as best aspossible. The SG6000F utilizes a filter matrix made up of 3 multi-octave tunable low frequency filters and two
fixed high-frequency low-pass filters. The SG6000 PRO has an additional fixed filter to cover its extra
bandwidth.

SwitchRF IN

2.2 - 4.4GHz

4.4 - 6GHzHarmonics are more plentiful at low frequencies (<500MHz) in wideband systems, causing more pronounced
distortion. The SG6000 filtering is typically able to reduce the second harmonic to -30dBc, and the third
harmonic to under -40dBc. Unfiltered synthesizers can have harmonics as high as -10dBc extending wellbeyond the 9th.

Remote Control Example CodeAll of our products can be controlled from any serial-capable programming language orenvironment. MATLAB, .NET, Linux, python are all popular. We use Visual Studio 2015 and C# for ourstandard GUI. First determine the port number that your device has installed itself as:

Example Code (C# .NET Framework):
using System;
using System.IO.Ports;// include serial port library

SerialPort myPort = new SerialPort( COM83 , 115200, System.IO.Ports.Parity.None, 8, System.IO.Ports.StopBits.One);
myPort.Open();// open the port we just mademyPort.WriteLine("*IDN?");// send any command here

myPort.ReadTimeout = 250;
string myResponse = myPort.ReadLine();System.Threading.Thread.Sleep(30);// read back the response// delay before sending the next command
