Model 2099-2424
10 MHz, 24V Source/Inserter
1.0 General
1.1 Equipment Description
The 2099-2424 10 MHz Source/Inserter is a 10 MHz, ± 0.01 ppm oven controlled crystal oscillator (OCXO)
with circuitry to insert the 10 MHz signal and DC voltage on L-band lines for an LNB and SSPB. Multi-
function switches select LNB and SSPB DC Power, internal or External 10 MHz, and insertion of 10 MHz on
the L-band lines. LEDs indicate DC power (green), Reference insertion (green), alarm (red), remote operation
(yellow), and OCXO oven warm-up (yellow). An external 10 MHz reference can be selected to be inserted
directly into the L-Band lines. Option E6 also allows the internal 10 MHz source to be locked to a high stability
external 10 MHz reference. Remote control allows remote configuration of front panel commands and
monitoring LNB and SSPB voltage and current. Parameter selection and LNB and SSPB voltage and current
appear on the LCD display. Connectors are BNC female for RF and 10 MHz input and output signals. AC
power is 100-240 ± 10% VAC, 47-63 Hz. The chassis is 1 RU, 12” deep.
