PXIe-5654 Front Panel and LEDs

This section describes the connectors and LED indicators on the PXIe-5654 RF Analog Signal Generator front panel.

Table 6. General Connector Descriptions
Connector Type Use
REF IN SMA An input terminal that routes an external reference signal to the PXIe-5654. This connector accepts a frequency range from 1 MHz to 20 MHz. REF IN has an input range of -5 dBm to +15 dBm and an input damage level of >+20 dBm.
REF OUT SMA An output terminal that routes a 10 MHz signal from the PXIe-5654. The device outputs the 10 MHz reference signal at +5 dBm, ±2 dBm.
REF OUT 2 SMA An output terminal that routes a 100 MHz signal from the PXIe-5654. The device outputs the 100 MHz reference signal at +5 dBm, ±2 dBm.
TRIG IN/OUT SMB An input/output terminal with a +3.3 V logic level high impedance input or low impedance output. This connector has a maximum input level of +5 V and an input damage level of ≤-0.5 V and ≥5.5 V.
Notice Do not apply an input signal to the TRIG IN/OUT connector when it is configured as an output or damage may occur.
PULSE IN SMB An input terminal that accepts a modulating square wave to pulse the RF output. PULSE IN has a +3.3 V logic level high impedance input. This connector has a maximum input level of +5 V and an input damage level of ≤-0.5 V and ≥5.5 V.
FM IN SMB An input terminal for frequency modulation with an input range of ±1 Vpk-pk. FM IN has an input damage level of ±2 V.
AM IN SMB An input terminal for amplitude modulation with an input range of ±1 Vpk-pk. AM IN has an input damage level of ±2 V.
ALC IN SMB If you use the PXIe-5654 with the PXIe-5696 Amplitude Extender, this terminal connects to the ALC OUT connector on the PXIe-5696. This connector has an input damage level of ±15 V.
RF OUT SMA An output terminal for the generated RF signal at the requested frequency and power level. This connector covers a frequency range from 250 kHz to 20 GHz.

LED Indications
ACCESS

Indicates the basic hardware status of the PXIe-5654 module.

Off—The module is not yet functional or has detected a problem with a PXI Express power rail.

Amber—The module is being accessed. Accessed means that the device setup transferred in order to control the device.

Green—The module is ready to be programmed.
ACTIVE

Indicates the state of the PXIe-5654 module:

Off—The module is not generating a signal.

Green—The module is generating a signal; applicable phase-locked loops (PLLs) are locked.

Red—The module has detected an error state; this may indicate a PLL lock failure or a thermal shutdown condition.
