Low Frequency Amplifier. LF AG1010 Jing Chen 2008-08-29 16:47 Configuration The device LF AG1010 is connected to a Moxa 5430 server. SICS client communicates with the Moxa 54530 server who sends and receives data packets to/from the LF AG1010 through a RS232 serial interface. Settings of the Moxa 5430 are Bits Per Second – 19200 Data Bits – 8 Parity – NONE Stop Bit – 1 Flow Controls – NONE Port Number – 4001 . Commands Commands for getting and setting values on the LF AG1010. Sending a command without a value will return the current value. Note that all power values are in deciwatts (dW). 1dW = 0.1Watt. lf_limits power Set forward power limit to power dW. lf_limits FPL 50 sets the forward power limit to 50dW lf_limits FPL returns the forward power limit Units: dW Range: 0 to 6000 lf_limits power Set reverse power limit to power dW lf_limits RPL 50 sets the reverse power limit to 50dW lf_limits RPL returns the reverse power limit Units: dW Range: 0 to 1600 lf_pagc power Set power level for AGC mode to power dW lf_pagc 50 sets the AGC mode power level to 50dW lf_pagc returns the AGC mode power level lf_pmgc power Set power level for MGC mode to power % MGC scale in % is for reference only. 0% - 0W, 100% full output. Not linear! This mode is for continues and pulsed operation. lf_pmgc 50 sets the MGC mode power level to 50% lf_pmgc returns the MGC mode power level Units: % Range: 0 to 100 lf_freq freq Set frequency to freq Hz Range: 20000 to 2000000 (20kHz to 2MHz) lf_burst modemode time time top top Set burst mode to mode BURST is possible in MGC Mode only!

Allowed Sweep mode OFF Sweep mode ON Change sweep parameters without changing sweep mode ON/OFF lf_meas Returns forward power, reverse power and temperature? start Hz Parameters N/A There are no parameters to set on this device. Description 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. 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. 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 1010’s power measurement system provides an accurate reading of VSWR. 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. 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. 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. Known Issues No know issues.
