Inputs and Outputs
Front panel connectors (all connectors are BNC unless otherwise stated)
RF output Output impedance 50 Ω (nom)
Option 513/520 Precision APC-3.5 male, or Type- N with Option 1ED
Option 532/540 Precision 2.4 mm male; plus 2.4—2.4 mm and 2.4-2.9 mm female adapters
Maximum reverse power 0.5 W, 0 Vdc
USB 2.0 Used with a memory stick for transferring instrument states, licenses and other
files into or out of the instrument. Also used with U2000 Series USB average power
sensors.
Rear panel connectors
Rear panel inputs and outputs are 3.3 V CMOS, unless indicated otherwise. CMOS inputs will accept 5 V CMOS, 3 V CMOS, or TTL
voltage levels.
RF output (1EM)
• Output impedance 50 Ω (nom)
• Option 513/520 : Precision APC-3.5 male, or Type- N with option 1ED
• Option 532/540: Precision 2.4 mm male; plus 2.4—2.4 mm and 2.4-2.9 mm female
adapters
Sweep out Generates output voltage, 0 to +10 V when the signal generator is sweeping. This
output can also be programmed to indicate when the source is settled or output pulse
video and is TTL and CMOS compatible in this mode. Output impedance < 1 Ω, can
drive 2 kΩ. Damage levels are ± 15 V.
Ext1 External AM/FM/PM #1 input: Nominal input impedance is 50 Ω/600 Ω/1MΩ
nominal: Damage levels are ± 5 V.
Ext2 External AM/FM/PM #2 input: Nominal input impedance is 50 Ω/600 Ω/1MΩ
nominal: Damage levels are ± 5 V.
Pulse External pulse modulation input. This input is TTL and CMOS compatible. Low logic
levels are 0 V and high logic levels are +1 V. Nominal input impedance is 50 Ω. Input
damage levels are ≤ –0.3 V and ≥ +5.3 V.
Trigger 1 (in) Accepts TTL and CMOS level signals for triggering point-to-point in sweep mode.
Damage levels are ≤ –0.3 V and ≥ +5.3 V.
Trigger 2 (out) Default use is with sweep mode. The signal is high at start of dwell, or when waiting
for point trigger in manual sweep mode; low when dwell is over or point trigger is
received. This output can also be programmed to indicate when the source is settled,
pulse synchronization, or pulse video. Outputs a 2.5V into 50 Ω nominal. Input damage
levels are ≤ –0.3 V and ≥ +5.3 V.
Reference input Accepts a 10 MHz reference signal used to frequency lock the internal time base.
Option 1ER adds the capability to lock to a frequency from 1 MHz to 50 MHz. Nominal
input level –3.5 to +20 dBm, impedance 50 Ω, sine or square waveform.
10 MHz out Outputs the 10 MHz reference signal used by internal timebase. Level nominally
+5 dBm. Nominal output impedance 50 Ω. Input damage level is +16 dBm.
ALC in This female BNC connector is used for negative external detector leveling.
• Input impedance: 100 kΩ (nominal)
• Signal levels: –0.2 mV to –0.5 V
• Damage levels: < –12 V and > 1 V
Z-Axis output This female BNC connector supplies a +5 V (nominal) level during retrace and band
switch intervals of a step or list sweep. During step or list sweep, this connector
supplies a –5 V (nominal) level when the RF frequency is at a marker frequency and
intensity marker mode is on. The load impedance should be ≥ 5 kΩ.
