E.
Telecommunications and broadcasting service carriers will encounter distorted signals caused
by adjacent channels' inter-modulation while transmitting modulated signals using
communications channels. If the distorted signals are too large the communications quality
of adjacent channels will be affected. The ACPR measurement can examine the leakage status
that is conducive to identifying interference source.
The OCBW measurement can simultaneously display OCBW, channel power and PSD.
OCBW's unit is shown by percentage. A measurement area containing bandwidth will be
shown when OCBW is in use.
SEM measures out-of-channel emission which is defined by corresponding in-channel power.
Users can set main channel's parameters, out-of-channel range, and limit line, etc.
GSP-9330 has the built-in SEM settings of 3 GPP, WLAN 802.11b/g/n, Wimax 802.16 and
self-defined communications system. SEM supports the Pass/Fail test function and lists
frequency range for surpassing each out-of-channel limit. An alarm signal will be triggered
if any measurement results that are not matched with SEM.

CNR/CSO/CTB
The built-in CNR/CSO/CTB functions of GSP-9330 are ideal for measuring performance of
CATV amplifier and system.
Note: General CATV is 75 . For GSP-9330, a 50 ~ 75 ohm adapter is needed.Ω
Phase Jitter
The Phase Jitter function can rapidly measure phase noise produced by RF signal source's
and oscillator's carrier deviation. This function can directly convert signal jitter to phase (rad)
and time (ns).
Marker Noise
The marker noise function calculates the average noise level over a bandwidth of 1Hz,
referenced from the marker position.
Radar or TDMA communications systems, via intermittently turning On/Off output power,
control transmission signals. In order to monitor the power spectrum during the transmission
process, the Gated Sweep function can initiate measurement only when signals appear. This
function is ideal for measuring burst signals such as GSM or WLAN.
Gated Sweep
Harmonic can easily measure the amplitude of fundamental frequency and as high as ten
orders of harmonic frequency. This function can also measure amplitude(dBc) which is the
ratio of harmonic and corresponding fundamental carrier. Total harmonic distortion(THD)
can also be calculated by this function. The best harmonic information can be obtained by
adjusting RBW.
Harmonic
Users can measure the linearity of non-linear systems and components such as receiver,
low-noise amplifier and mixer by TOI which automatically tests effective carrier and measures
inter-modulation sidebands.
TOI (Third Order Intercept)
Users can go to zero span setting and open marker to observe burst signals when measuring
burst signal in time domain is required.
