| Precision frequency reference | Aging rate: ±5 × 10–10/day |
| Narrow resolution bandwidth (FFT) | 1 Hz to 1 KHz |
| Digital resolution bandwidth (RMS detection) | Adds RMS detection and expands resolution bandwidth to 10 Hz to 1 MHz. |
| Ethernet interface | Allows external control via 10BASE-T. |
| I/Q unbalanced input | - Mounts 2 connectors for I/Q synch inputs and operating inputs (BNC type) to the front panel. - Measurement software corresponding to I/Q input is required for actual measurement. |
| Power Meter | - With upper frequency of 32 GHz, measure from -20 to +20 dBm. - Add range expansion option to measure from -30 to +20 dBm. |
| 4 GHz LO output. | Outputs internal 2nd local signal through rear connector. |
| Auto power recovery | - Disables the power switch on the front panel. - Power is automatically reset after the line is restored. |
| Rack mount (IEC) without handles | - Mounts an IEC standard rack mount. - Eliminates the standard tilt handle. |
| Rack mount (JIS) without handles | - Mounts a JIS standard rack mount. - Eliminates the standard tilt handle. |
