| •FEATURES |
| 1. |
The RF frequency covers a wide range of 100 kHz to 170 MHz. |
| 2. |
Two systems of low-distortion, fixed oscillators are provided as
AF oscillators, and the AM/FM and the L and R of FM stereo can be set
to different frequencies. |
| 3. |
The variable DDS oscillator is provided allowing arbitrary AF frequencies
to be specified in 1-Hz resolution. |
| 4. |
The AM modulation supports up to 100 %, and FM modulation up to 200 kHz.
In addition, a wide bandwidth of external modulation up to 100 kHz is
supported for both AM and FM. |
| 5. |
Equipped with a simultaneous AM/FM modulation function. |
| 6. |
FM stereo modulator is equipped. |
| 7. |
Oscillation frequency is locked to a high-accuracy reference oscillator to ensure
accuracy of ±5x10-6 (5 ppm). |
| 8. |
The solid-state step attenuator is used for the RF output system to extend service
life (because there is no mechanical contact), and is suited to frequent changes in
output level such as in automatic production and inspection applications. |
| 9. |
The output level can be set in the range of -20 dBµ to 126 dBµ
(0 dBµ = 1 µV, 50  into open circuit) in 0.1 dB steps. |
| 10. |
Since the GPIB interface is provided as standard, this instrument can be incorporated
into a GPIB measurement system. |
| 11. |
An SCA input connector and a PILOT output connector are provided for connecting an
external FM multiple signal modulator such as a RDS modulator. (S1 version) |
| 12. |
The numeric keys are used for setting the frequency, output level, and modulation factor. |
| 13. |
Up to 100 preset conditions consisting of frequency, output level, and modulation
can be stored to internal memory. |
| 14. |
All front panel switches (except power switch) can be remotely controlled via the 24-pin
connector on the rear panel. |

(The deviation at AF=400 Hz/1 kHz is reduced by approximately
20 dB when pre-emphasis is turned ON. This is to avoid saturation
of the modulation path. The deviation approaches 0 dB according to
the Pre-emphasis characteristics as the AF frequency increases.) |
