Phase modulation
(Option UNT)
Modulation deviation and frequency response:
Max deviation 3 dB bandwidth
Nominal bandwidth N x 5 radians (nom) DC to 1 MHz (nom)
High bandwidth mode N x 0.5 radians (nom) DC to 4 MHz (nom)
Resolution 0.1% of deviation
Deviation accuracy < +0.5% + 0.01 rad (typ)
1 kHz rate, normal bandwidth mode
Distortion
< 0.2% (typ)
1 kHz rate, deviation normal bandwidth mode
Sensitivity when using
external input
+1V peak for indicated deviation (nom)
Amplitude modulation 1
(Option UNT)
AM Depth Linear Exponential
Maximum settable 90% 20 dB
Resolution 0.1% of depth (nom) 0.01 dB (nom)
Accuracy (1 kHz rate) < ±4% of setting <±(4% of setting
+ 1% (typ) + 0.2 dB) (typ)
Modulation rate (3 dB bandwidth, 30% depth)
DC coupled 0 to 10 kHz (typ)
AC coupled 5 Hz to 10 kHz (typ)
Distortion (1 kHz rate, 30% depth) < 2.0% (typ)
Sensitivity when using
external input
+1V peak for indicated depth (nom)
1. AM is specified at carrier frequencies > 2 MHz, ALC on, and when AM envelope does not exceed max
power or go below –15 dBm for Option 520 or –20 dBm for Option 540.
