The output of AUDIO_OUT_HI can be set on the RF Analyzer page.

AM_MOD J1(20)

AM MOD Ouptut Z	< 400 Ω	Load 100 kΩ/4000 pF
Full Scale output	4 Vp
Uncalibrated Path Gain	2.37 ± 1.5%	DAC=255, 1 kHz Gain (AFG1 Path)
Gain (F.P. Input)	5.12 ± 2.5%	DAC=255 , 1 kHz
Attenuator Accuracy	± 0.02 dB	( 1 kHz) (20 dB)
High Freq roll off	< 3 dB	150 kHz
Low Freq roll off	< 1 dB	20 Hz AM port EXT AC Standard AM load.

To route the input signal AFG1 to the output AM_MOD, access the SERVICE Screen. Select the latch ’dstr_mod_destination’ and change the value to any odd number (for example ’3’). Select ’dstr_afg1_to_mod’ and change the value to any even number (for example ’2’) and measure.

MOD_MON J1(18)

Output Z

< 1 k Ω

MOD_MON can also be accessed using the SERVICE Screen. Use latch ’dstr_monitor_select’.

’2’ signal at un-attenuated values of AFG1.

’3’ use external source connected to ’Modulation_In_AmSpeech’ ’4’ signal at levels set up at RF Generator page.
