Typically <0.5% for deviations up to 1 radian at 1 kHz Modulation source Internal LF generator or external via front panel BNC AMPLITUDE MODULATION FOR CARRIER FREQUENCIES 2 GHZ Range 0 to 99.9%, 0.1% resolution Accuracy ±5% of set depth at 1 kHz (at +17°C to 27°C ambient temperature), temperature coefficient <±0.02%/°C 1 dB bandwidth DC to 30 kHz (DC coupled) 10 Hz to 30 kHz (AC coupled) 20 Hz to 30 kHz (AC coupled with ALC) Distortion <2.5%* at 1 kHz rate for modulation depths up to 80% and <1.5% at 1 kHz rate for modulation depths up to 30% *<3.5% for carrier freqs above 500 MHz Modulation source Internal LF generator or external via front panel BNC PULSE MODULATION FOR FAST PULSE MODULATOR SEE OPTIONS Frequency range 32 MHz to 2.51 GHz, useable to 10 MHz RF output range Maximum guaranteed output is reduced to +8 dBm (+20 dBm or +14 dBm with high power option when pulse modulation is selected) RF level accuracy When pulse modulation is enabled, adds ±0.5 dB to the RF level accuracy specification On/off ratio Better than 45 dB below 1.2 GHz, better than 40 dB above 1.2 GHz Rise and fall times Less than 10 ìs Control Pulse input is on a rear panel BNC with 10 kÙ nominal input impedance. A HCT logic 0 (0 V to 0.8 V) turns the carrier off, a HCT logic 1 (2.0 V to 5 V) turns the carrier on. Max safe input is ±15 V MODULATION OSCILLATOR The modulation oscillator signal is available on a front panel BNC connector at a level of 2 V RMS EMF from a 600 Ù source impedance. Frequency range 0.01 Hz to 100 kHz Resolution 5 digits. Minimum resolution 1 Hz Frequency accuracy As frequency standard Distortion Less than 0.1% THD at 1 kHz Waveforms Sine wave to 100 kHz Square wave useable to 50 kHz Triangle wave useable to 20 kHz INTERNAL FUNCTION GENERATOR In function generator mode, the modulation oscillator output may be varied in frequency and level. Internal modulation is disabled in this mode. Level range 1 mV to 4 V RMS EMF Resolution 1 mV Source Impedance 600 Ù nominal Level Accuracy at 1 kHz ±5% + 5mV Frequency Response Better than ±1 dB relative to 1 kHz EXTERNAL MODULATION Input on the front panel via BNC connector. 1 V RMS (1.414 V pk) sine wave for set deviation. Input sensitivity may be optionally specified for 1 V pk (option 10). Input impedance is 100 kÙ nominal. MODULATION ALC The external modulation input can be levelled by a peak levelling ALC system over the input voltage range of 0.5 V to 1.25 V RMS sine wave. High and low indicators on the display indicate when the input is outside the levelling range.
