<title>Description</title>
<para>The AG 1010 produces up to 1,000 Watts of power over a frequency range from lower than
20 kHz to higher than 1.2 MHz. It operates over the entire frequency range without band
switching or other adjustments. Extended range to over 2 MHz is possible with reduced
output power. Gain is rated at 60 dB with a typical gain flatness of ±1.5 dB.</para>
<para> The Front Panel offers a LCD display of Forward, Reflected and Load Power readings,
RF Status, MGC/AGC setups and operating frequency in Generator Mode.</para>
<para> Power meters are calibrated into a 50 Ohm Load and are accurate when unit operates
into matched load. Outside of matched condition, the model AG 1010s power measurement
system provides an accurate reading of VSWR.</para>
<para> When used as amplifier, the AG 1010 is compatible with most signal and function
generators, computer synthesizer cards and accurately reproduces all waveforms within
its output and bandwidth limits.</para>
<para>The Forced-air cooling system and the internal power supply are designed to permit
operation over a wide range of temperature and global AC line conditions. The AG 1010 is
built to withstand a +5 dBm (1.2Vp-p) Input signal. The unit amplifies the inputs of AM,
FM, SSB, pulse and other complex modulations. </para>
<para>OUTPUT PROTECTION AG 1010 is protected by its internal control system for 1,000 Watts
of total Forward Power and 160 Watts of Reflected Power. This will protect the amplifier
output stage from accidental overdrive at the input and an extreme mismatch at the
Output.</para>
