1. Introduction
1.1 General
The PeakTech®1007 / 1014 / 1016 series is a high-performance direct digital synthesize (DDS)
function generator with very low noise and distortion. Combined with the DDS technology, the
FG700S/F series can output high accuracy and stable frequency to meet your test requirement
of precision and accuracy. The build-in trigger/gate function allows you to control the waveform
generation by internal or external. Also, the PSK and FSK modulation gives you the ability to
generate such waveform for experiment or communication purpose. The FG700F series comes
with AM/FM module and frequency counter to make the function of this product more
comprehensive.
1.2 Key Features
• Direct digital synthesize multi-function generator
• Sine, square, triangle, pulse, DC, synchronize and ramp up/ramp down output
(only P 1014 / 1016)
• Ultra low noise and low distortion (down to 1mV peak signal)
• PSK and FSK modulation
• Digital setting of linear or logarithm sweep function
• Trigger and gate function
• AM/FM module (only P 1014 / 1016)

The actual logarithm sweep step ratio is calculated by following equation:
Actual Ratio = Fn +1
= 1 + Setting Ratio Step Sweep Logarithm
Fn1000
For Example, if the logarithm sweep step ratio setting is set to 5 and the Fnis 1000Hz, the
actual ratio is the following:
5___
Actual Ratio =1 + 1000 = 1.005
The Fn+1, Fn+2 and Fn+3 are the following:
Fn +1 = Actual Ratio × Fn= 1.005 ×1000Hz = 1005Hz
Fn + 2 = Actual Ratio × Fn +1 = 1.005 ×1005Hz = 1010.025Hz
F n +3 = Actual Ratio × Fn + 2 = 1.005 ×1010.025Hz = 1015.075125Hz
Note : The maximum value of the logarithm sweep step ratio setting is 10.0 and the minimum
value of the logarithm sweep step ratio setting is 0.0001.
Linear Sweep Time Setting
Logarithm Sweep Time Setting
The sweep time sets the delay time between two frequencies step. It is set from 1 to 1000. The
higher value will put longer delay of two frequencies step.
