HP 8655A Synchronizer/Counter

Item Condition: USED
Price: 46.000 HUF + ÁFA


SPECIFICATIONS
Counter Characteristics

Range: 1 kHz to 520 MHz
Sensitivity: 100 m Vrms (-7 dBm), ac coupled into 50 ohms.
(Typically -20 dBm, 10 kHz to 200 MHz).
Maximum input: ac: 707 m Vrms (+10 dBm) for accurate count.
dc: ?25 Vdc. Both inputs are protected with common fuse.
Count resolution : 6-digit LED display
Mode Normal x10 EXPAND1
1 kHz to 10 MHz (EXTERNAL) 10 Hz 1 Hz
10 to 520 MHz (EXTERNAL & SYNCHRONIZE COUNT) 1 kHz 100 Hz

Accuracy : ?1 count ? time base accuracy.

Time Base Characteristics

Frequency: 1 MHz temperature-compensated crystal oscillator.
Aging (constant ambient temperature): 0.1 ppm/hr., 2 ppm/90 days.
Temperature: ?5 ppm from 0° to 50°C (Referenced to 25°C.)
Typical Overall Accuracy (after 2 hours warm-up and within 3 months of calibration): Better than ? 2 ppm from 15° to 35°C (Option 001 higher stability time base available.)
Real Output: 1 MHz, nominally 0.5 volts peak-to-peak 500 ohms.
External Reference Input: 1MHz, nominally 0.5 volts peak-to-peak into 1000 ohms (Not available with Option 001 high stability time base.)

Synchronization Characteristics

Frequency Range: 10 to 520 MHz
Frequency Count Resolution: 1 kHz, or 100 Hz in x10 EXPAND.
Frequency Loccsan Resolution : 1 kHz, depressing LOCK +500 Hz button allows a locked resolution of 500 Hz.
Frequency Accuracy : same as time base accuracy.
Lock Time Duration (after 5 minute warm-up, constant ambient): 45 min. typical
FM Rate While Synchronized : 50 Hz to 25 kHz
FM Accuracy (with 8654B only):
[Total FM Accuracy] = [8654B FM Accoracy] ? [Frequency Correction Error]
Frequency correction error² is typically 4%

_________________________________________________________________

¹ Will continue to accurately count from 1 to 10 MHz and from 100 to 520 MHz with loss of most significant digit (indicated by overflow light). Phase lock is not allowed.
²Frequency correction error is a function of the unlocked 8654B freqency drift. For optimum FM accuracy, this error may be eliminated by unlocking, retuning to the desired frequency, and relocking.
