Engineered for dependable performance in satellite and RF distribution systems, the PL7240 delivers clean, linear L-Band transport with tight amplitude flatness across typical channel bandwidths. It sustains strong carrier-to-noise and spurious-free dynamic range to protect constellation quality and link margins. Low profile transmitter and receiver modules are hot swappable and mount in the PL7010 chassis with redundant power and passive cooling for high availability.
What is the operating frequency range of the PL7240?
It covers 950 to 3000 MHz, supporting both uplink and downlink signal transmission within this range.
What is the maximum transmission distance?
The link supports fiber runs up to 10 km within a 4 dB optical budget, with options for 1550 nm or CWDM lasers for longer distances.
How does PL7240 maintain signal integrity across L Band?
It holds amplitude flatness to ±0.25 dB over any 36 MHz channel, achieves >100 dB Hz2⁄3 SFDR with 20 dBm OIP3, delivers >57 dB CNR in a 36 MHz bandwidth, and keeps group delay variation under 1.5 ns.
Are the PL7240 modules hot-swappable?
Yes. Both transmitter and receiver modules can be replaced while the system remains active, ensuring maximum uptime.
How is the system managed and monitored?
Operators can control and monitor key parameters locally through the front-panel LCD or remotely via SNMP, including optical power, RF levels, and LNB voltage.
