signal available on the rear panel Auxiliary connector.
RF burst attenuation requires Electronic Attenuator Opt 003.
The internal modulation source is capable of generating up to two
simultaneous signals into any one of the modulation systems.
Frequency Range
0.1 Hz to 50 kHz (16 MHz with Option 005) with 0.1 Hz or 5 digits of
resolution
Accuracy
As frequency standard
Distortion
< 0.1 % for a sine wave at 1 kHz
In addition to a sine wave the following waveforms can be generated:
Triangle 0.1 Hz to 10 kHz (2 MHz with Option 005)
Ramp 0.1 Hz to 10 kHz (2 MHz with Option 005)
Square 0.1 Hz to 5 kHz (1 MHz with Option 005)
(Note: modulation frequency can be set to 50 kHz irrespective of
waveform type)
Level
Modulation source signals are available on the rear panel I/AM OUT
and Q/FM OUT at nominal level of 1 V peak EMF from 50
source
impedance.
External inputs are available with a selectable input impedance of
50
or 100 k (default setting), AC or DC coupled.
Apply 1 V RMS (default) or 1 V peak for the set modulation.
A HI/LO indicator when the applied signal is greater than ± 6% from
nominal
External AM is input to EXT I/EXT AM front panel BNC connector.
External FM is input to EXT Q/EXT FM front panel BNC connector.
A high performance Dual Arbitrary (ARB) Waveform Generator that pro-
vides IQ signals for the IQ modulator
The ARB enables files to be downloaded with sample rates from
17 kHz to 66 MHz. The ARB uses an interpolation system to increase
the digital to analog converter sample rate and avoid the use of re-
construction filters.
