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
OTHER INPUTS/OUTPUTS

Trig In DC coupled External Trigger Input signal used for step Sweep changes in Point Trigger mode
Input Threshold: 1.65V nominal. Trigger polarity can be set to Negative Edge or Postive Edge
Input Protection Maximum/minimum external applied voltage is +6V or –1V.
Sync Out Rear panel output SYNC signal goes to its active state when generator output frequency & level have settled within specification after a step change during Sweep. SYNC returns to inactive state at end of specified dwell period
Active Output Level: +5V (Active state set to ‘Pos’) or 0V (Active state set to ‘Neg’)
Output Impedance: 50 Ohm Minimum load impedance is also 50 Ohm
Output Protection: Output will withstand accidental short circuit to ground and applied external voltages up to +5V.
Compact half-rack 2U casing uses minimum bench space
Full remote control through RS232, USB, LAN and GPIB
Significantly lower cost than other 6GHz generators
