The Anritsu / Wiltron 68369B Synthesized Signal Generator is a microprocessor-based, synthesized signal sources with high resolution phase-lock capability. It generates both discrete CW frequencies and broad (full range) and narrow band sweeps across the frequency range of 10 MHz to 40 GHz. All functions of the signal generator is fully controllable locally from the front panel or remotely (except for power on/standby) via the IEEE-488 General Purpose Interface Bus (GPIB).
| CW Mode |
| Output |
Twenty independent, presettable CW frequencies (F0 – F9 and M0 – M9) |
| Accuracy |
Same as internal or external 10 MHz time base |
| Internal Time Base Stability |
With Aging: |
<2 x 10 -8 /day (<5 x 10 –10 /day with Option 16) |
| With Temperature: |
<2 x 10 -8 /C over 0C to 55C (<2 x 10 -10 /C with Option 16) |
| Resolution |
1 kHz (0.1 Hz with Option 11) |
| External 10 MHz Reference Input |
Accepts external 10 MHz 100 Hz, 0 to +10 dBm time base signal. Automatically disconnects the internal high-stability time-base option, if installed. BNC, rear panel, 50 Ohmn impedance |
| 10 MHz Reference Output |
0.5 Vp-p into 50 Ohmn, AC coupled. Rear panel BNC; 50 Ohmn impedance |
| Switching Time (typical maximum) |
<40 ms to be within 1 kHz of final frequency |
| Analog Sweep Mode |
| Sweep Width |
Independently selected from 1 MHz to full range continuous sweep |
| Accuracy |
The lessor of: 30 MHz or (2 MHz + 0.25% of sweep width) for sweep speeds of ≤50 MHz/ms. |
| Sweep Time Range |
30 ms to 99 seconds |
| Phase-Locked Step Sweep Mode |
| Sweep Width |
Independently selected, 1 kHz (0.1 Hz with Option 11) to full range. Every frequency step in sweep range is phase-locked |
| Accuracy |
Same as internal or external 10 MHz time base |
| Resolution (Minimum Step Size) |
1 kHz (0.1 Hz with Option 11) |
| Steps |
User-selectable number of steps or the step size |
| Number of Steps |
Variable from 1 to 10,000 |
| Step Size |
1 kHz (0.1 Hz with Option 11) to the full frequency range of the instrument. (If the step size does not divide into the selected frequency range, the last step is truncated.) |
| Dwell Time Per Step |
Variable from 1 ms to 99 seconds |
| Switching Time (typical maximum) |
<15 ms + 1 ms/GHz step size or <40 ms, whichever is less |
| Alternate Sweep Mode |
| Sweeps alternately in analog or step sweep between any two sweep ranges. Each sweep range may be associated with a different power level |
| Manual Sweep Mode |
| Provides stepped, phase-locked adjustment of frequency between sweep limits. User-selectable number of steps or step size.
360B VNA SOURCE LOCK MODE |
| Under control of the ANRITSU 360B Vector Network Analyzer, the synthesized signal generator is phase-locked at a typical <8.5 ms/step sweep speed. Frequency resolution is limited to 100 kHz |
