Model HP 8340 A Specifications and Supplemental Peiformance Characteristics (14of15)
NEG BLANK
Rear panel BNC female connector. Supplies negative rectangular pulse (approximately -5 Vdc into 2
kOhm load) during the retrace and band switch points of the
Z-AXIS BLANK/MKRS
Rear panel BNC female connector. Supplies positive rectangular pulse (approximately +5 V de into 2
kOhms) during the retrace and band switchpoints of the RF output. Also, supplies a -5 Vdc pulse when
the RF is coincident with a marker frequency (intensity markers only).
AUX OUT
Rear panel Type-N female connector. Provides a 2.3 to 7.0 GHz fundamental oscillator output,
nominally 0 dBm and 50 Ohm output impedance.
For further information refer to the Front/Rear Panel functional group in Section VIII.
All functions (except line power) may be programmed via the Hewlett-Packard Interface Bus (HP-IB).
Detailed Remote operation information is included in Section III, Operation.
ENVIRONMENTAL
Temperature: Operation at 0 to +55°C, except as noted in electrical specifications.
Passes 5 day cycling, +40°C, 95% relative humidity.
Humidity:
EMI: Conducted and radiated interference is within the requirements of CE03 and RE02 (relaxed by 10
dB) of MIL STD 461A, and within the requirements of VDE 0871/1978, Level B and CISPR publication
11 (1975).
WARM-UP TIME
Operation: Requires 30-minute warmup from cold start, 0 to +55°C . Internal temperature equilibrium is
reached after 2-hour warmup at stable outside temperature.
Frequency Reference:
instrument connected to the ac power. For instruments disconnected from ac power for less than 24
hours, the aging rate is <l x 10-9/day after a 72-hour warmup.
POWER REQUIREMENTS
Standard Instrument:
47.5 to 66 Hz; 100, 120, 220, or 240 volts (±10%); 500 VA maximum (40 VA in STANDBY).
003, 400
Option Hz operation:
360 to 440 Hz, 100 or 120 volts (±10%)
