Overview

The TGR6000 is a low-cost RF signal generator with a maximum frequency of 6GHz. It is intended for CW (carrier wave) applications where modulation is not required. and avoids the costs associated with adding modulations.

Low phase noise is matched by low leakage. low residual FM and spurii. The internal timebase has a 1ppm stability. and an external frequency reference can be used for higher precision.

The output amplitude and/or frequency can be swept over the full range of each in a single sweep. The instrument can be set up to perform two types of sweep. The first sweep type is a Step Sweep in which the start and stop conditions are defined. together with the number of points in the sweep. linear or logarithmic spacing between points. and a dwell time at each point.

 



The other sweep type is a List Sweep in which up to 1000 points are defined in a list. with the frequency. level and dwell time specified for each point. Both types of sweep can be free run or triggered by a Sweep Trigger from a variety of sources; in addition. a Point Trigger can be defined for each individual step of the sweep. A rear panel SYNC output signal indicates when the output is stable. and can be user-programmed to be high or low.

The output level can be adjusted to correct for external equipment frequency response using the TRIM function. The TRIM function consists of a user programmable list of up to 100 amplitude adjustment /frequency pairs. 

The instrument provides non-volatile storage for up to 12 instrument setups and up to 16 sweep lists.
The instrument is remotely controllable via LAN. USB. RS232 or GPIB.

FREQUENCY and AMPLITUDE SWEEP

Step Sweep Step frequency and/or amplitude according to a formula over a specified number of points.  Formula Specifies: Frequency start/stop. Amplitude start/stop.
Dwell time at each step – programmable 0.01 to 10.000sec
Max Points: 1000
Sweep Run: Continuous or single. Sweep up or down
Step Spacing: Linear or logarithmic
Sweep Triggering: Manual. Ext. signal. timed (0.1 – 999.9sec) or via remote interface
Sync Signal: (Output Stable) available during dwell time. Programmable to be high or low
List Sweep As for Step Sweep except that a user defined table of frequency. amplitude and dwell time values defines the steps. The table can be created within the instrument or downloaded via the remote interfaces.
Max Points: 1000
List Storage: Up to 16 Sweep Lists can be stored permanently within the instrument
Point Trigger Each point in a sweep (step or list) can be subject to a trigger event rather than a dwell time.
Point Triggering Manual. Ext. signal or via remote interface.
TRIM (User Level Compensation Tables)
  A table of frequency/gain pairs allows the user to modify the generator output level with respect to frequency to calibrate an entire test set up or improve the calibration of the generator alone. The table can be created within the instrument or downloaded via the remote interfaces.
Max Points: 100
