• Level accuracy                  better than 1.5% in range ( Sine/Vrms/50Ω )
• Output level:                      Sine and Triangular waves 50Ω : <-70dBm to +10 dBm with internal attenuator, about -110 dBm when external attenuator added. Square wave ( 50Ω ) : < +240 mVp to + 5 Vp, ref.to ground. Squarewave rise time : < 13nS , fall : < 1.5 nS , duty cycle : 50:50 
• Pulse Generator                on/off time adjustable from 10μS to 65 s (ONtime/ OFF time , Burst , Go, Quit ).
• Attenuator                          only for sine and triangular waves,from 0 dB to 60 dB,accepts additional 40 dB of external attenuator.
• Operation through On-Off switch,Rotary Encoder w/switched schaft for Enter and two potentiometers,one for Sine/Triangle control,the other for Square.
• All indications on a 2X16 ch.blue LCD display module.
• Scroll/ Enter control will take to : step,mode,output on/ off, high Z/50Ω,sweep,settings,calibrate,quit.
• Sine / Triangular measurement units are : mVrms,mVp/p,mVp and dBm (the former only for 50Ω load).
• All outputs on 3 SMA female receptacles,one for pulse/burst,the second for sine/triangle,the third for square waves.
• Based on a DDS chip and dedicated software.
• Precision time base ( 25MHz) with state of the art circuitry to eliminate ref.drift.
• All outputs short circuit protected.
