L-TRX/L-19F
106 / 234 H172203_1_001
2H-REC IN (J1, SMA):
2H receiver input from 2H preamplifier (HPPR/2, AQS 1H2H, LOCK-OUT)
• Maximum input power with no damage: +0 dBm
REF IN (J3, SMA):
Reference clock input from AV4 REFERENCE board or L-19F REF OUT (J3).
• Nominal input power @ 160 MHz: -0.5 ±0.5 dBm.
• Nominal input power @ 320 MHz: -3.5 ±0.5 dBm.
TP-F0 OUT (J4, SMA):
Transmitter pulse output to HPPR preamplifier (via AV4 PSM-A board).
• 5V TTL output, no damage with 50 ohm load.
(pulse polarity see Service Web [}110])
BLNKTR-2H~ IN (J5, SMA):
Power amplifier blanking pulse from AV4 TRX (via NanoBay backplane or AV4 PSM-A
board).
• 5V TTL input
(high (+5 V) = power amplifier blanked, low (0 V) = power amplifier gated)
SEL-2H/AMP~(J6, SMA):
Power amplifier control signal from AV4 GTU unit (SEL_2H/DEC).
• 5V TTL input
(high (+5 V) = 2H Lock, low (0 V) = 2H amplifier selected for gradient shimming, 2H Lock
muted)
2H IN (J8, SMA):
Power amplifier input RF-signal from AV4 TRX.
• Maximum input power with no damage: +10 dBm.
2H-TR OUT (J9, N):
2H RF-output to HPPR preamplifier (2H TRANSM) or L-19F unit (2H-TR IN) depending on
configuration.
• Transmitter output specification see Technical Data BSMS/2 Lock Transceiver [}99].
